By using CPATH you are working around it. Additionally by relying on external environment variables it is not obvious from the build files what will actually be built (for readers of these files). Just use include_directories() to add the include dirs you need. If you have a lot of them, you can create a macro which sets them all and just call that macro once from your toplevel cmake file. If you care mainly about the current directory, you can do: set(CMAKE_INCLUDE_CURRENT_DIR ON) Alex _______________________________________________ CMake mailing list CMake@cmake.org http://www.cmake.org/mailman/listinfo/cmake
