# Fixes a compiler-problem when using PCH - the /Ym flag is adjusted by the compiler in MSVC2012,
# hence we need to set an upper limit with /Zm to avoid discrepancies)
# (And yes, this is a verified, unresolved bug with MSVC... *sigh*)

# Note: This workaround was verified to be required on MSVC 2017 as well
