Support for both OpenSSL 1.0 LTS and OpenSSL 1.1 versions.
Many Linux distributions are still on 1.0 and will stay on LTS for quite
some time.
Port of CMaNGOS commit: e1b0048f05
* Required for handling flags inherited by linked projects
correctly in the corresponding precompiled header.
* Reduces the maintenance effort for precompiled headers
(cherry picked from commit 92f96fc10e)
* Remove the usage of global flags and definitions
set through the CMAKE_CXX_FLAGS variable.
* Use cmake target compile features for setting the
CXX standard automatically.
* Make C++14 globally available in the project
* Closes#21033
(cherry picked from commit e60c1f84a7)
* *PCH.cpp are now only compiled with MSVC, other compilers use custom helper commands to generate the precompiled header
* Don't call the linker for pch helpertargets
* I wasn't able to work arround a path which contains spaces,
since it seems like a CMake specific issue.
* Closes#16947
(cherry picked from commit 42eeb28a8b)
* Makes it possible to define the linkage for every module
* Move the ScriptPCH into the root directory
* Changes the SCRIPTS cmake variable to a string type:
-> -DSCRIPTS=0 is -DSCRIPTS="minimal-static" now
(builds commands and spells statically)
-> -DSCRIPTS=1 is -DSCRIPTS="static" now
(builds all modules statically)
-> -DSCRIPTS="dynamic"
(builds all modules dynamically)
-> Also the default value which is provided by the SCRIPTS
variable is overwriteable through the SCRIPTS_COMMANDS,
SCRIPTS_SPELLS... variable.
* Set the default option to hierarchical
* Add a new "hierarchical-folders" option which enables folders inside IDE's.
(cherry picked from commit bf773ccc41)
* to make use of cmakes inherited link dependencies which
imports all include directories/ definitions from the link library
(cherry picked from commit 1a572d2425)
* A PCH is still generated for every target which was passed to the macro
* Resolves naming conflicts when using the same PCH header from multiple projects
* Ref #15671
(cherry picked from commit a974574d6e)
