I can only get this to happen by running CMake on a build tree that already exists. The variable *does* get used on the *first* run in a fresh tree. It does *not* get used later because you don't need to specify it to regenerate. CMake has already recorded a rule to load the file in CMakeFiles/CMakeSystem.cmake and does not support changing the toolchain of an existing build tree. IOW, this is a legitimate instance of the warning. -Brad _______________________________________________ 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
