When generating VS2010 targets with CMake, I would like the /LTCG flag turned on (only for release + releasewithdebinfo if possible, but its okay if its on for debug builds). How do I modify the linker flags? add_definitions() doesn’t work because that only modifies compiler flags. And yes, I have wrapped it in if(MSVC).
How do I modify the linker flags?
You can modify the linker flags in MSC using #pragma comment(linker, …)
However, if you’d like to do it in the build process with cmake, here are the names you need to know:
CMAKE_EXE_LINKER_FLAGSCMAKE_SHARED_LINKER_FLAGSCMAKE_MODULE_LINKER_FLAGS(Thanks to Cmake.org).
