Hi Eric,

Just when exactly do you set these variables. As the name of these
variables suggest, these are initialisation variables. When CMake
processes the PROJECT() command, it also configures the compilers that
you define there (C and C++ by default). After that, none of the changes
you make to these *_INIT variables will be picked up.

HTH,
Marcel Loose.
