CFLAGSΒΆ
This is a CMake Environment Variable. Its initial value is taken from the calling process environment.
Add default compilation flags to be used when compiling C
files.
CMake uses this environment variable value, in combination with its own
builtin default flags for the toolchain, to initialize and store the
CMAKE_C_FLAGS
cache entry.
This occurs the first time a build tree is configured for language C
.
For any configuration run (including the first), the environment variable
will be ignored if the CMAKE_C_FLAGS
variable is already defined.
