This behavior has been introduced to fix the issue described here: http://public.kitware.com/Bug/view.php?id=12957 On a build machine i noticed that each CMake run gets slower and slower. After deleting all directories in build\CMakeFiles\CMakeTmp the speed got back to normal. I used the process monitor (from sysinternals) and saw that CMake enumerates all items in the build\CMakeFiles\CMakeTmp quite often. I don't know why, but i think that's the reason for the decreasing speed. Steps to Reproduce: 1. delete the CMakeCache.txt file if it exists 2. Run cmake -G "Visual Studio 9 2008" . with CMakeLists.txt: PROJECT(HelloWorld C CXX) this detects the compiler and leaves several directories in CMakeFiles\CMakeTmp. 3. goto step 1 ====================================================================== Issue History Date Modified Username Field Change ====================================================================== 2012-04-23 03:28 Andreas Roth New Issue ====================================================================== -- 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
