CFLAGSΒΆ

New in version 3.10.

This is a CMake Environment Variable. Its initial value is taken from the calling process environment.

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

See also CMAKE_C_FLAGS_INIT.
