[CMake] Problem with CMAKE_AUTOMOC files not being regenerated or cleaned

[Glenn Coombs]

I select "Clean Solution" from the Build menu which is a complete clean.
The output looks like this:

1>------ Skipped Clean: Project: INSTALL, Configuration: Debug Win32 ------
1>Project not selected to build for this solution configuration
2>------ Clean started: Project: ALL_BUILD, Configuration: Debug Win32
------
3>------ Clean started: Project: yuv_player, Configuration: Debug Win32
------
4>------ Clean started: Project: yuv_player_automoc, Configuration: Debug
Win32 ------
5>------ Clean started: Project: ZERO_CHECK, Configuration: Debug Win32
------
========== Clean: 4 succeeded, 0 failed, 1 skipped ==========

The yuv_player_automoc project looks like it is being cleaned but the
associated moc_*.cpp and yuv_player_automoc.cpp files are never deleted.
After doing a "Clean Solution" and manually deleting the
yuv_player_automoc.cpp file a build works as expected:

1>------ Build started: Project: ZERO_CHECK, Configuration: Debug Win32
------
2>------ Build started: Project: yuv_player_automoc, Configuration: Debug
Win32 ------
1>  Checking Build System
2>  Automoc for target yuv_player
1>  CMake does not need to re-run because
C:/data/perforceCheckouts/sim/tools/yuvplayer/DEV/glenn.coombs/cmake/CMakeFiles/generate.stamp
is up-to-date.
2>  Generating moc_ctrlBasic.cpp
2>  Generating moc_ctrlmenu.cpp
2>  Generating moc_infoWin.cpp
2>  Generating moc_imageDisplay.cpp
2>  Generating moc_imageDisplayGL.cpp
2>  Generating moc_imageDisplayQt.cpp
2>  Generating moc_multiWindow.cpp
2>  Generating moc_videoGeneric.cpp
...

with the moc_*.cpp files being regenerated.  If I don't manually delete the
yuv_player_automoc.cpp file then the moc_*.cpp files are never regenerated
even if they are out of date compared to the header files they are
generated from.
