Summary0013160: try_compile leaves temporary directories
DescriptionI installed the version 2.8.8 of CMake and i noticed that each try_compile run leaves a directory like build\CMakeFiles\CMakeTmp\cmTryCompileExec78340897.dir.

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 Reproduce1. 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
