RCFLAGS

Default compilation flags to be used when compiling resource files. Will only be used by CMake on the first configuration to determine resource default compilation flags, after which the value for RCFLAGS is stored in the cache as CMAKE_RC_FLAGS. For any configuration run (including the first), the environment variable will be ignored if the CMAKE_RC_FLAGS variable is defined.
