I don't know but.... The TRY_COMPILE statement inside CheckFunctionExists.cmake should generate a warning about that? May be (not tested) turning warning to error will make CHECK_FUNCTION_EXISTS to fail? For GCC this could be SET(CMAKE_REQUIRED_FLAGS "-Werror") but this is not portable :-( -- Erk _______________________________________________ CMake mailing list CMake@cmake.org http://www.cmake.org/mailman/listinfo/cmake
