Sure, the find_program() call in FindQt4.cmake has registry keys first, but if you look at the docs for find_program(), all of those paths are looked at last. The CMAKE_PREFIX_PATH and PATH variables have a higher priority, and you can set those to control which Qt you want found. -- Clinton Stimpson Elemental Technologies, Inc Computational Simulation Software, LLC www.csimsoft.com _______________________________________________ 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
