You can set the variable to "NOTFOUND" (and FORCE it in the cache) to make FIND_XXX() run again. But I think you shouldn't do this, it's a feature. Why do you use FIND_XXX() multiple times with the same variable ? Alex _______________________________________________ CMake mailing list CMake@cmake.org http://www.cmake.org/mailman/listinfo/cmake
