Are you proposing new keyword arguments to find_* commands to specify this? The problem is that find modules don't necessarily know which kind of binary the application wants. That is why we have the CMAKE_FIND_ROOT_PATH_MODE_<type> variables. The existing CMAKE_FIND_ROOT_PATH* and CMAKE_SYSROOT options have been sufficient for most packages for a long time. We regularly get complaints that FindPythonLibs does not ask the python executable where to get its libraries, and our answer every time is that it is wrong to do that for cross compiling. FindQt4 is making that mistake, and that is the cause of these troubles. FindQt4 should be taught not to ask qmake for anything when cross compiling. -Brad -- Powered by www.kitware.com Please keep messages on-topic and check the CMake FAQ at: http://www.cmake.org/Wiki/CMake_FAQ Kitware offers various services to support the CMake community.
