This should not be the case. If it were, then our Continuous dashboards would frequently fail the test on their 2nd and later runs during a day... but this test very rarely fails on the Continuous dashboards. > Seems like a bug in the cmake file for the test. The code for this test is difficult to understand. It all happens at configure-time of the test project via execute_process in the CMakeLists file. Maybe there is a subtle problem in the test's code itself, but if so, it's subtler than I can see... This test has been around for a very long time, since before we had "cmake --build" on the command line. Perhaps it should be re-written using cmake --build or ExternalProject to make it easier to understand. The intent behind the test is simply to ensure that changing a header file results in the proper re-compiling of c++ files that include it when the change is followed by an incremental build. -- 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://public.kitware.com/cgi-bin/mailman/listinfo/cmake-developers
