Turning on linker flags with CMake

Question

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)

Answer 1

For adding linker flags - the following 4 CMake variables:

CMAKE_EXE_LINKER_FLAGS
CMAKE_MODULE_LINKER_FLAGS
CMAKE_SHARED_LINKER_FLAGS
CMAKE_STATIC_LINKER_FLAGS

can be easily manipulated for different configs (debug, release...) with the ucm_add_linker_flags macro of ucm

linker flags can also be managed on a per-target basis - by using target_link_libraries and passing flags with a - in front of them (but not with a -l - that would be treated as a link library and not a link flag).
