A modern build system -like CMake provides enough context information to have the build system generate and update -these files automatically. - -#### non-intrusive - -The configuration of precompiled headers usage and single computation unit builds belongs to the -build system and not in the source code. Nobody wants to litter one's source files with `hdrstop` -pragmas or be forced to add an include directive to every file. Source code should build properly -when a precompiled header isn't used and should build faster when a precompiled header is used. - -#### minimal interface - -Maintaining a build system over time is enough work and the CMake language may often get in your -way. Thus the solution should only add few public CMake functions. It should be easy to integrate -it into an existing CMake based build system and it should be just as easy to remove it again. - -#### lazy file creation - -The additional source files needed for precompiled header support and unity build support should -only be created when they are required for the compilation of a target. Thus the solution should -not create these files upon configuring the project, but should set up custom build commands for -the creation of these files that only kick in when the files are required to exist by the build -process. - -#### cross-platform - -C/C++ Compilers and IDEs on different platforms vary widely in how the implement precompiled -header support. The solution should hide these implementation details and present a uniform -interface to the developer on all supported platforms. - -cotire basic usage ------------------- - -Cotire consists of a single CMake module file, which can be easily added to an existing CMake -project. - -The file `CMake/cotire.cmake` needs to be copied to the module directory of a CMake project.

From the example project that ships with cotire: - - add_executable(example main.cpp example.cpp log.cpp log.h example.h) - ... - cotire(example) - -Cotire looks at the properties of the target provided by CMake (e.g., target type, source files, -compile flags, preprocessor defines, include directories, ...) and modifies the target's build -process in the following way: - -1. cotire adds a custom build rule to produce a unity source file from the target's sources. -2. cotire adds a custom build rule to produce a prefix header file by tracking the header files - included by the target's sources. -3. cotire adds a custom build rule to produce a precompiled header from the prefix header. -4. cotire modifies the target's compile flags to make use of the generated precompiled header. -5. cotire adds a couple of new targets. - -For makefile based build systems, running `make help` in the terminal reveals the new targets: - - $ make help - ... - ... all_pch - ... all_unity - ... clean_cotire - ... example - ... example_pch - ... example_unity - -The `example_pch` target triggers the compilation of the precompiled header and as a side effect -the generation of the unity source and the prefix header. The target `clean_cotire` cleans up all -files generated by cotire. The `example_unity` target produces the same output as the original -`example` target, but does so by performing a unity build. The `all_pch` and `all_unity` serve as -pool targets for all cotired project targets. - -By default, the `example_unity` target inherits all build settings from the original target -`example` including linked libraries and target dependencies. - -cotire generated files ----------------------- - -For a target that has been cotired, three files will be generated as part of the build process: - -### the unity source - -The unity source file is generated from the target by querying the target's `SOURCES` property. -It consists of preprocessor include directives for each of the target source files. The files -are included in the same order that is used in the CMake `add_executable` or `add_library` call. -Header files are omitted. - -This is a unity source generated for the example project under OS X: - - #ifdef __cplusplus - #include "/Users/sakra/Documents/cotire/src/main.cpp" - #include "/Users/sakra/Documents/cotire/src/example.cpp" - #include "/Users/sakra/Documents/cotire/src/log.cpp" - #endif - -The unity source file uses absolute paths to include the target's source file. The file is not -intended to be portable across different build folders or machines. It is an intermediate file -tied to the build folder that is automatically recreated by the build system if it is missing. - -For multi-core machines cotire can be configured to generate multiple unity file segments that -can be built in parallel by the chosen CMake generator (see below). - -### the prefix header - -The prefix header is produced from the unity source file by running the unity file through the -preprocessor and keeping track of each header file used (this is done by using option `-H` with -GCC / Clang and `/showIncludes` with Visual Studio C++). The path of each used header file is -compared against an exclude directory list and an include directory list to decide if the header -file should be added to the prefix header. - -By default the include directory list is empty and the exclude directory list is initialized to -`"${CMAKE_SOURCE_DIR};${CMAKE_BINARY_DIR}"`. This default setting guarantees that project headers -which are likely to be changed frequently are not added to the prefix header. - -Upon generation of the prefix header cotire makes sure that target compile options, include path -settings and preprocessor defines (e.g., `NDEBUG`) that affect the outcome of the preprocessor -are correctly set up. - -Generating the prefix header from the unity source is much faster than running each individual -target source file through the preprocessor, because the coalesced unity source will make the -preprocessor process most header files only once. - -This is a prefix header produced for the example project with Visual Studio 2013 under Windows 7: - - #pragma warning(push, 0) - #ifdef __cplusplus - #include "C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\include\string" - #include "C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\include\algorithm" - #include "C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\include\iostream" - #endif - #pragma warning(pop) - -Generating the prefix file under Ubuntu 12.04 with GCC 4.6 yields the following result: - - #pragma GCC system_header - #ifdef __cplusplus - #include "/usr/include/c++/4.6/string" - #include "/usr/include/c++/4.6/algorithm" - #include "/usr/include/c++/4.6/iterator" - #include "/usr/include/c++/4.6/iostream" - #endif - -Using Xcode 5.1 under OS X 10.9, this is the resulting prefix header: - - #pragma clang system_header - #ifdef __cplusplus - #include "/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/c++/v1/string" - #include "/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/c++/v1/iostream" - #endif - -Besides include directives, cotire also adds compiler specific pragmas to the generated prefix -header to suppress compiler warnings upon inclusion. - -Cotire attempts to produce a minimal list of header files by omitting header files indirectly -included by a header that is already part of the prefix header. Header files with nonstandard -file extensions like `.inl`, `.inc` of `.ipp` are omitted by default. - -The generated prefix file includes the selected header files by their absolute paths. This speeds -up the precompiling of the prefix header because the compiler does not have to search for header -files in include directories again. - -The prefix header is tailored to the CMake target that it is generated for. It is tied to the -compiler environment of the local machine and is not portable across different compilers or -machines. It is automatically recreated by the build system if it goes missing. - -The generated prefix header can be applied to a different target added in the same source directory -(see below). - -Optionally, cotire will also create a prefix source file that consists of a single include directive -for the prefix header. This file is needed for pre-compiling the prefix header with Clang or GCC -to make both compilers handle the `system_header` pragma correctly. - -### the precompiled header - -The precompiled header is produced from the generated prefix header by using the proprietary -precompiling mechanism depending on the compiler used. For GCC and Clang cotire sets up a custom -build rule and generates the precompiled header as described in the documentation for -[GCC][gcc_pch] and [Clang][clang_pch]. Cotire then modifies the `COMPILE_FLAGS` property of the -target to force the inclusion of the prefix header. - -Visual Studio C++ and Intel C++ use a [different approach][msvc_pch] to pre-compiling. Both -compilers require a host source file to generate the precompiled header as a side effect of -producing an object file. Cotire modifies the `COMPILE_FLAGS` of the first target source file to -[generate][msvc_pch_create] the precompiled header and then modifies the `COMPILE_FLAGS` of the -remaining target source files to [include][msvc_pch_use] the generated precompiled header. - -For Xcode projects generated with CMake, cotire completely hands off the pre-compilation of -the prefix header and the inclusion of the precompiled header to the IDE. Cotire attaches a -pre-build action to the target which generates the unity source file and the prefix header. -Cotire then modifies Xcode attributes of the generated Xcode project to have Xcode precompile the -the generated prefix header with the Xcode build steps `ProcessPCH` for C sources and -`ProcessPCH++` for C++ sources. - -For precompiled headers creation flags must match use flags exactly. Cotire uses the same flags, -include directories and preprocessor defines that are used for the compilation of source files -for the generation of the precompiled header. Thus the resulting precompiled header binary is only -usable for the target and cannot be re-used for a different CMake target. - -cotire advanced usage ---------------------- - -### applying cotire to multiple targets at the same time - -The `cotire` function can be applied to multiple targets added in the same source directory in one -call: - - add_library(libA STATIC ...) - add_library(libB SHARED ...) - add_executable(example ...) - ... - cotire(example libA libB) - -### mixed-language targets - -Cotire is able to speed up the build process of mixed language targets, consisting of both C and -C++ sources. It generates a separate set of unity source files, prefix headers and precompiled -headers for both languages and modifies the `COMPILE_FLAGS` of each target source file to include -the correct precompiled header depending on the compilation language of the source file. - -### obtaining the names of the generated files and targets - -For a cotired target the target properties `COTIRE_<LANG>_UNITY_SOURCE`, -`COTIRE_<LANG>_PREFIX_HEADER`, `COTIRE_<LANG>_PRECOMPILED_HEADER` will be set to the paths of the -generated files (`<LANG>` can be set to `CXX` or `C`). The target property -`COTIRE_UNITY_TARGET_NAME` will be set to the name of the generated unity target: - - cotire(example) - ... - get_target_property(_unitySource example COTIRE_CXX_UNITY_SOURCE) - get_target_property(_prefixHeader example COTIRE_CXX_PREFIX_HEADER) - get_target_property(_precompiledHeader example COTIRE_CXX_PRECOMPILED_HEADER) - get_target_property(_unityTargetName example COTIRE_UNITY_TARGET_NAME) - -If a source file's `COMPILE_FLAGS` are modified by cotire, it sets the source file property -`COTIRE_TARGET` to the name of the target, that the source file's build command has been -altered for: - - cotire(example) - ... - get_source_file_property(_cotireTargetName "example.cpp" COTIRE_TARGET) - if (_cotireTargetName) - message(STATUS "example.cpp has been cotired for target ${_cotireTargetName}") - endif() - -### changing the name of the generated unity build target - -By default cotire uses the name of the the original target with the suffix `_unity` appended -for the name of the generated unity build target. To create the unity build target under a -different name, set the `COTIRE_UNITY_TARGET_NAME` property: - - add_executable(example_template main.cpp example.cpp log.cpp log.h example.h) - set_target_properties(example_template PROPERTIES COTIRE_UNITY_TARGET_NAME "example") - ... - cotire(example_template) - -Invoking the `example` target will then run the unity build. - -### restricting cotire to certain build configurations - -To restrict the cotire related modifications to the build process to certain build configurations, -the `CONFIGURATIONS` parameter can be added to the `cotire` call. - - cotire(example CONFIGURATIONS Release MinSizeRel) - -For single build type builds the selected configuration will be checked at configure time, for -multi-configuration builds the check will be done at build time. - -It is recommended to have at least one build configuration that does not make use of cotire to -ensure that the project builds properly without cotire. - -### disabling precompiled headers and unity builds - -If the target's build process should not be modified to make use of the generated precompiled -header, the target property `COTIRE_ENABLE_PRECOMPILED_HEADER` can be set to `FALSE`: - - set_target_properties(example PROPERTIES COTIRE_ENABLE_PRECOMPILED_HEADER FALSE) - cotire(example) - -If a unity build target should not be added by cotire, the target property -`COTIRE_ADD_UNITY_BUILD` can be set to `FALSE`: - - set_target_properties(example PROPERTIES COTIRE_ADD_UNITY_BUILD FALSE) - cotire(example) - -The property `COTIRE_ADD_UNITY_BUILD` only affects the addition of the unity build target. Custom -build rules for the generation of the unity source file will always be set up, because the -unity source file is needed for the generation of the prefix header. - -Both properties default to `TRUE`. If both are set to `FALSE`, cotire will only set up custom build -rules for the generation of the unity source and the prefix header. - -The properties `COTIRE_ENABLE_PRECOMPILED_HEADER` and `COTIRE_ADD_UNITY_BUILD` can also be set on -directories. A target inherits the property value from its enclosing directory. - -### disabling precompiled headers for small targets - -The cache variable `COTIRE_MINIMUM_NUMBER_OF_TARGET_SOURCES` can be set to the minimum number of -source files required to enable the use of a precompiled header. It defaults to 3. To override the -default, run `cmake` with the following options: - - $ cmake -D COTIRE_MINIMUM_NUMBER_OF_TARGET_SOURCES=5 <path-to-source> - -### using a manually maintained prefix header instead of the automatically generated one - -cotire can be configured to use an existing manually maintained prefix header (e.g., Visual Studio -projects often use a prefix header named `stdafx.h`) instead of the automatically generated one. -Set the target property `COTIRE_CXX_PREFIX_HEADER_INIT` to the path of the existing prefix header -file. The path is interpreted relative to the target source directory: - - set_target_properties(example PROPERTIES COTIRE_CXX_PREFIX_HEADER_INIT "stdafx.h") - cotire(example) - -If the prefix header `stdafx.h` needs an accompanying source file (e.g., `stdafx.cpp`) in order -to be precompiled properly, that source file needs to be the first one on the list of source -files in the target's `add_executable` or `add_library` call. - -The property `COTIRE_CXX_PREFIX_HEADER_INIT` can also be set to a list of header files which will -then make up the contents of the generated prefix header. - -A manually maintained prefix header will always be applied to the corresponding target, -even if the target contains too few sources to enable the use of a precompiled header. - -### using a generated prefix header for multiple targets - -A prefix header that is generated for a cotired target can be applied to a different target -added in the same source directory: - - cotire(example) - get_target_property(_prefixHeader example COTIRE_CXX_PREFIX_HEADER) - ... - set_target_properties(other_target PROPERTIES COTIRE_CXX_PREFIX_HEADER_INIT "${_prefixHeader}") - cotire(other_target) - -The compilation of either target will trigger the generation of the prefix header. - -### configuring the generation of the prefix header - -There are multiple target properties which affect the generation of the prefix header: - -* `COTIRE_PREFIX_HEADER_IGNORE_PATH` can be set to a semicolon separated list of directories. If a -header file is found in one of these directories or sub-directories, it will be excluded from the -generated prefix header. - -* `COTIRE_PREFIX_HEADER_INCLUDE_PATH` can be set to a semicolon separated list of directories. If -a header file is included from one of these directories or sub-directories, it will be included -in the generated prefix header. - -If a header file is matched by both `COTIRE_PREFIX_HEADER_IGNORE_PATH` and -`COTIRE_PREFIX_HEADER_INCLUDE_PATH`, the option which yields the closer relative path match wins. -For example, if third-party libraries are part of the source tree in a directory called `Libs`, -the following setting will make cotire select header files from the third-party directory, but -ignore other project related headers in `CMAKE_SOURCE_DIR`: - - set_target_properties(example PROPERTIES - COTIRE_PREFIX_HEADER_IGNORE_PATH "${CMAKE_SOURCE_DIR}" - COTIRE_PREFIX_HEADER_INCLUDE_PATH "${CMAKE_SOURCE_DIR}/Libs") - -The properties `COTIRE_PREFIX_HEADER_IGNORE_PATH` and `COTIRE_PREFIX_HEADER_INCLUDE_PATH` can -also be set on directories. - -The following cache variables also affect the selection of prefix headers: - -* Directory paths in `COTIRE_ADDITIONAL_PREFIX_HEADER_IGNORE_PATH` will be added to the list of -ignored directories when the prefix header file is created. - -* `COTIRE_ADDITIONAL_PREFIX_HEADER_IGNORE_EXTENSIONS` can be used to ignore header files by file -extension. It defaults to the CMake list `inc;inl;ipp`. - -During development, changes to the project source files may affect the list of header files that -should be selected for inclusion in the prefix header (e.g., a standard include may be added or -removed from a target source file). Cotire does not automatically recreate the prefix header, -when a target source file is changed, because this would always trigger a re-compilation of the -precompiled header and would result in a rebuild of the whole target. To make the prefix header -creation dependent on changes to certain target source files, the source file property -`COTIRE_DEPENDENCY` can be set to `TRUE` for those files: - - set_property (SOURCE "example.cpp" PROPERTY COTIRE_DEPENDENCY "TRUE") - -### fixing linkage issues - -When a C++ program uses `extern "C"` on a system header file, cotire will not be able to detect -that the include file needs C linkage and will include the file with C++ linkage in the generated -prefix header instead. For example, the C interface to BLAS `cblas.h` usually has to be included -as `extern "C"` in a C++ program: - - extern "C" { - #include <cblas.h> - } - -The presence of `extern "C"` includes will prevent cotired targets from being linked successfully -because of unresolved function references using the wrong linkage. To work around the problem, -the property `COTIRE_PREFIX_HEADER_IGNORE_PATH` can also include the full path of header files -besides directories. Here is an example: - - set_property(DIRECTORY - PROPERTY COTIRE_PREFIX_HEADER_IGNORE_PATH - "${ATLAS_INCLUDE_DIR}/cblas.h" - "${CMAKE_SOURCE_DIR}" "${CMAKE_BINARY_DIR}") - -That way `cblas.h` will not be included in the generated prefix header and will not cause problems -upon linking. - -### using a manually maintained unity source instead of the automatically generated one - -Cotire can be configured to use an existing manually maintained unity source file instead of the -automatically generated one. Set the target property `COTIRE_CXX_UNITY_SOURCE_INIT` to the path -of the existing unity source file. Its path is interpreted relative to the target source directory: - - set_target_properties(example PROPERTIES COTIRE_CXX_UNITY_SOURCE_INIT "example-all.cpp") - cotire(example) - -The property can also be set to a list of source files which will then make up the contents of -the generated unity source file. - -### configuring the generation of the unity source - -By default cotire adds all target source files to the generated unity source. In most cases a -unity build will not work out of the box, because unity builds [break][EoUB] the use of some C -and C++ language features. Unity build problems can be tackled in the following way: - -* Change the order of the source files in the `add_executable` or `add_library` calls. -Problematic source files should be moved towards the end. - -* Set the source file property `COTIRE_EXCLUDED` on problematic source files. The source file -will not be included in the unity source file and will be compiled separately when the unity build -is performed. - -* `COTIRE_UNITY_SOURCE_EXCLUDE_EXTENSIONS` can be used to exclude source files by file extension -from inclusion in the generated unity source. It defaults to the CMake list `m;mm`. - -* If the unity source file is too large and the compilation process runs into a compiler limit, -the target property `COTIRE_UNITY_SOURCE_MAXIMUM_NUMBER_OF_INCLUDES` can be set. If the target -contains more than that number of source files, cotire will create multiple unity source files -for it. Each unity source file is compiled separately when the unity build is performed. -The property is initialized by value of the cache variable -`COTIRE_MAXIMUM_NUMBER_OF_UNITY_INCLUDES`. - -* Another way to break up a large unity source file is to set the source file property -`COTIRE_START_NEW_UNITY_SOURCE` to `TRUE` on selected target source files. If cotire encounters -this property, it will complete the current unity file and start a new one. The new unity source -file will include the source file as the first one. This property essentially works as a separator -for unity source files. - -### optimizing the build process for multiple processor cores - -To make use of all the machine's CPU cores for the unity compilation of a target, the target -property `COTIRE_UNITY_SOURCE_MAXIMUM_NUMBER_OF_INCLUDES` can be set to the string `-j`. Cotire -will then create as many unity file segments as there are CPU cores on the machine. Because -the unity file segments do not depend on each other, a multi-core aware build process can compile -the file segments in parallel. - -To explicitly specify the number of cores, append the number after `-j`, e.g. `-j 4` or `-j4`. - -For CMake generators that are multi-core aware by default (i.e., Visual Studio, JOM, Ninja), cotire -will automatically initialize the property to `-j`. For makefile based generators, this has to be -done explicitly by setting the cache variable `COTIRE_MAXIMUM_NUMBER_OF_UNITY_INCLUDES`, i.e.: - - $ cmake -D COTIRE_MAXIMUM_NUMBER_OF_UNITY_INCLUDES=-j4 <path-to-source> - $ make -j 4 - -### fixing macro definition clashes - -Many unity build problems stem from macro definitions leaking into other target source files, -where they may conflict with other definitions of the same name. Cotire adds the properties -`COTIRE_UNITY_SOURCE_PRE_UNDEFS` and `COTIRE_UNITY_SOURCE_POST_UNDEFS` to fix macro definition -clashes. - -As an example, if these properties are set on a source file of the example project: - - set_source_files_properties (example.cpp PROPERTIES - COTIRE_UNITY_SOURCE_PRE_UNDEFS "max;min" - COTIRE_UNITY_SOURCE_POST_UNDEFS "DEBUG_TYPE") - -This will make cotire add undefs to the generated unity source file. - - #ifdef __cplusplus - #include "/Users/sakra/Documents/cotire/src/main.cpp" - #undef min - #undef max - #include "/Users/sakra/Documents/cotire/src/example.cpp" - #undef DEBUG_TYPE - #include "/Users/sakra/Documents/cotire/src/log.cpp" - #endif - -The properties `COTIRE_UNITY_SOURCE_PRE_UNDEFS` and `COTIRE_UNITY_SOURCE_POST_UNDEFS` can also be -set on targets. Cotire will add `#undef` directives for each source file in the unity source then. - -### enabling verbose builds - -The cache variable `COTIRE_VERBOSE` can be set to `TRUE` to see all compile commands used when -generating the cotire related files. Cotire will also print the contents of the generated unity -source and the prefix header for verbose builds. `COTIRE_VERBOSE` defaults to `FALSE`. -When using a Makefile generator `COTIRE_VERBOSE` defaults to the value of the makefile variable -`VERBOSE` (i.e., `make VERBOSE=1`). - -### conditionally loading cotire - -To make a `CMakeLists.txt` robust against a missing `cotire.cmake` module, the following strategy -can be applied to using cotire: - - include(cotire OPTIONAL) - ... - add_executable(example main.cpp example.cpp log.cpp log.h example.h) - ... - if (COMMAND cotire) - cotire(example) - endif() - -The `include(cotire OPTIONAL)` will prevent CMake from raising an error if cotire cannot be -found. The actual calls to cotire need to be guarded by `if (COMMAND cotire)` blocks. - -### using cotire with compiler wrappers - -Cotire is compatible with CMake compiler wrappers. For example, the use of [ccache][ccch] may be -enabled in the following way upon configuring the project: - - $ export CC="/usr/local/bin/ccache /usr/bin/gcc" - $ export CXX="/usr/local/bin/ccache /usr/bin/g++" - $ export CCACHE_SLOPPINESS=pch_defines,time_macros - $ cmake .. - -Alternatively, for CMake 3.4 or later compiler wrappers can be enabled by pointing the CMake -variable `CMAKE_CXX_COMPILER_LAUNCHER` to the compiler wrapper executable upon configuring: - - $ cmake -D CMAKE_CXX_COMPILER_LAUNCHER=/usr/local/bin/ccache <path-to-source> - -Note that with ccache in order for precompiled headers to work properly, it is necessary to set -the environment variable `CCACHE_SLOPPINESS` to `pch_defines,time_macros`. Otherwise the build -process may abort with the following error message: - - fatal error: file 'example_CXX_prefix.hxx' has been modified since the precompiled header - 'example_CXX_prefix.hxx.gch' was built - -Also see the [ccache manual][ccch_pch]. - -### applying cotire to object library targets - -CMake 2.8.8 introduced a new type of library target called [object library][objlib]. An object -library is a convenience target that compiles multiple source files but does not create a linked -target library for them, e.g.: - - add_library(myLib OBJECT lib1.cpp lib2.cpp lib3.cpp) - add_executable(exeA $<TARGET_OBJECTS:myLib> mainA.cpp) - add_executable(exeB $<TARGET_OBJECTS:myLib> mainB.cpp) - -The `cotire` function can be applied to an object library target in a familiar fashion: - - add_library(myLib OBJECT lib1.cpp lib2.cpp lib3.cpp) - cotire(myLib) - # use unity object library for executables - add_executable(exeA $<TARGET_OBJECTS:myLib_unity> mainA.cpp) - add_executable(exeB $<TARGET_OBJECTS:myLib_unity> mainB.cpp) - -Because object library targets do not support `PRE_BUILD` actions, precompiled header usage cannot -be enabled for them for Xcode projects generated with CMake. Unity builds work as expected, though. - -### automatically setting up linked libraries in the unity target - -The setting of the target property `COTIRE_UNITY_LINK_LIBRARIES_INIT` controls the linking -strategy for the generated unit target. - -If this property is empty or set to `NONE`, the generated unity target's link libraries have to be -set up manually with subsequent `target_link_libraries` calls: - - set_target_properties(example PROPERTIES COTIRE_UNITY_LINK_LIBRARIES_INIT "NONE") - ... - cotire(example) - target_link_libraries(MyExecutable_unity ${MyExecutableLibraries}) - -If this property is set to `COPY`, the unity target's link libraries will be copied from the -original target. - -If this property is set to `COPY_UNITY`, the unity target's link libraries will be copied from the -original target but instead of copying a linked target verbatim, the target's corresponding unity -target will be preferred, provided one exists. This also applies to object libraries, which have -been added to the original target with a `TARGET_OBJECTS` generator expression. - -As of cotire 1.7.0, the default linking strategy for unit targets is `COPY_UNITY`. - -The property `COTIRE_UNITY_LINK_LIBRARIES_INIT` can also be set on directories. A target inherits -the property value from its enclosing directory. To make all targets in the project use the -`COPY` strategy, the directory property can be set in the outermost `CMakeList.txt` file: - - include(cotire) - ... - set_property(DIRECTORY PROPERTY COTIRE_UNITY_LINK_LIBRARIES_INIT "COPY") - -### using cotire with Qt - -Cotire is compatible with both Qt4 and Qt5 projects that use CMake as build system. - -If a CMake target's `AUTOMOC` or `AUTOUIC` properties are set, the generated unity target will -automatically add a dependency to the implicitly generated `<targetname>_automoc` target to ensure -that `moc` and `uic` are run on the individual source files. - -The unity target will also include the implicitly generated `<targetname>_automoc.cpp` source file. - -The `Patches` directory contains examples for the [Qt4][fsedit_qt4] and [Qt5][fsedit_qt5] based -variants of the *FSEditor* sample Qt application. - -### installing files generated by unity targets - -Cotire cannot set up a `install_unity` target that mimics the `install` target automatically, -because CMake does not provide the necessary information about the existing install rules -programmatically. - -When using a Makefile generator, you can use the following workaround (thanks to peterhuene): - - $ make all_unity - $ make install/fast - -The `install/fast` does not trigger a build, but will use the binaries built by the `all_unity` -target. - -For other generators, set up an `install_unity` target manually. First set up install rules for -all unity targets, that mimic the install rules for the original targets: - - install(TARGETS example_unity RUNTIME DESTINATION "bin" OPTIONAL COMPONENT "unity") - -This installs the `example` executable built by the unity target to the `bin` folder. The install -rules for unity targets must use a custom install component. Then add a global `install_unity` -target that performs the installation of all unity targets: - - add_custom_target(install_unity - COMMAND ${CMAKE_COMMAND} -DCOMPONENT=unity -P cmake_install.cmake - COMMENT "Install the unity-built project..." - WORKING_DIRECTORY ${CMAKE_BINARY_DIR}) - add_dependencies(unity_install example_unity) - -The global `install_unity` target must depend on all unity targets that should be installed. - -### customized inclusion of system headers - -If a system header ends up in a precompiled header, it is not possible to customize the inclusion -of that header in a source file through preprocessor defines. - -For example, under Windows one may want to include `Windows.h` with `NOMINMAX` defined to prevent -the definition of the `min` and `max` macros: - - #define NOMINMAX - #include <Windows.h> - -The dependency of `Windows.h` on the preprocessor define `NOMINMAX` will not be picked up by cotire -automatically upon adding `Windows.h` to the prefix header. To work around the problem, make the -dependency explicit by using `add_definitions` in the corresponding `CMakeLists.txt`: - - if (WIN32) - # prevent definition of min and max macros through inclusion of Windows.h - add_definitions("-DNOMINMAX") - endif() - -That way, the preprocessor define `NOMINMAX` will be picked up by cotire and applied to the -pre-compilation of the prefix header. - -### organize includes added to the prefix header - -Sometimes the order of the includes in the automatically generated prefix header may result in -compilation errors due to subtile header dependencies. - -To work around the problem, the target property `COTIRE_PREFIX_HEADER_INCLUDE_PRIORITY_PATH` -can be set to a list of directories. Header files whose path matches one of these directories will -be inserted at the beginning of generated prefix header. Header files are sorted according to -the order of the directories in the property. Headers not matching one of these directories are -left untouched. - -The property `COTIRE_PREFIX_HEADER_INCLUDE_PRIORITY_PATH` can also be set on directories. A target -inherits the property value from its enclosing directory. - -common pitfalls ---------------- - -### include the `cotire.cmake` module correctly - -If CMake issues the message `Unknown CMake command "cotire"`, double check that the cotire module -has been included correctly in your project. See the manual section "cotire basic usage". - -### do not modify a target's build related properties after applying cotire - -Cotire only considers build related settings of a target at the time of the `cotire` function call. -If target properties that control the build are changed after the call to the `cotire` function, -the build rules set up by cotire for the precompiled header and unity build may not work correctly. - -Don't do this: - - add_executable(example main.cpp example.cpp log.cpp log.h example.h) - cotire(example) - ... - set_target_properties(example PROPERTIES POSITION_INDEPENDENT_CODE ON) # affects build - - -### always apply cotire in the same source directory where a target has been added - -CMake targets are globally visible. Nevertheless, it is important that the `cotire` function is -called for a target in the exact same directory that creates the target with `add_library` or -`add_executable`. - -Don't do this: - - add_subdirectory(src) - ... - cotire(mytarget) # mytarget added in src directory - -Cotire may fail to inspect the target's source files correctly, if the target has been added in a -different directory and you may get odd messages about missing source files. - -known issues ------------- - -### Ninja compatibility - -Under Ninja indirect prefix header dependencies are ignored by the generated build system. Cotire -uses the `IMPLICIT_DEPENDS` option of `add_custom_command` to make the precompiled header depend -on header files indirectly included by the prefix header.
