[CMake] Setting COMPILE_FLAGS property on a target in only debug?

[Petr Kmoch]

Unfortunately, this only works for single-configuration generators
(Makefiles). If you're targetting Visual Studio as well, you're pretty
much out of luck. I see this as one of the major issues with cmake.

A possible workaround is to move the target(s) in question to a
separate CMakeLists.txt included via add_subdirectory(). Then, you can
override the variable CMAKE_<LANG>_COMPILE_FLAGS_DEBUG in that
CMakeList.
