Or you can use CONFIGURE_FILE to create "wrappers" which #include the actual source file. If it's always the same flags, you can do it statically, using something like this: wrap_foo.c: /* -------------------------- */ /* clean up */ #ifdef DINT #undef DINT #endif #ifdef DLONG #undef DLONG #endif /* compile for int */ #define DINT #include "foo.c" #undef DINT /* compile for long */ #define DLONG #include "foo.c" #endif /* -------------------------- */ Michael _______________________________________________ Powered by www.kitware.com Visit other Kitware open-source projects at http://www.kitware.com/opensource/opensource.html Please keep messages on-topic and check the CMake FAQ at: http://www.cmake.org/Wiki/CMake_FAQ Follow this link to subscribe/unsubscribe: http://www.cmake.org/mailman/listinfo/cmake
