LDFLAGS

Will only be used by CMake on the first configuration to determine the default linker flags, after which the value for LDFLAGS is stored in the cache as CMAKE_EXE_LINKER_FLAGS_INIT, CMAKE_SHARED_LINKER_FLAGS_INIT, and CMAKE_MODULE_LINKER_FLAGS_INIT. For any configuration run (including the first), the environment variable will be ignored if the equivalent CMAKE_<TYPE>_LINKER_FLAGS_INIT variable is defined.
