Dangit really wish I would follow through further somtimes solution 2) did not work. I NEED to include those definitions at the beginning, or the target_link_libraries don't have the libraries....> and in that include, I NEED CMAKE_COMPILER_IS_GNUCC to be set correctly... so what then, break everything into a proper root project that adds all the related projects? Is there a variation of add_subdirectory that will take a filename? I guess it's just add a PROJECT above the include... but after set_property.... There's probably a really good reason why this can't be better protected with warnings around using things that work without ANY projects, but won't work before PROJECT in a cmake script. _______________________________________________ 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
