How to set the LDFLAGS in CMakeLists.txt?

Question

I set the CFLAGS in CMake by CMAKE_C_FLAGS. Is something like this to set LDFLAGS?

Answer 1

If you want to add a flag to every link, e.g. -fsanitize=address then I would not recommend using CMAKE_*_LINKER_FLAGS. Even with them all set it still doesn't use the flag when linking a framework on OSX, and maybe in other situations. Instead use link_libraries():

add_compile_options("-fsanitize=address")
link_libraries("-fsanitize=address")

This works for everything.
