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

[Glenn Coombs]

No, the yuv_player_automoc.cpp file is not removed on a clean (nor are the
other moc_*.cpp files).  Having just modified ctrlBasic.cpp and ctrlBasic.h:

$ ls -ltr moc* ../ctrlMenu/ctrlBasic.*
-rwxr-xr-x+ 1 glenn.coombs Domain Users  4366 Apr 25 15:04
moc_ctrlBasic.cpp*
-rwxr-xr-x+ 1 glenn.coombs Domain Users 11912 Apr 25 15:04 moc_ctrlmenu.cpp*
-rwxr-xr-x+ 1 glenn.coombs Domain Users  8203 Apr 25 15:04 moc_infoWin.cpp*
-rwxr-xr-x+ 1 glenn.coombs Domain Users  3508 Apr 25 15:04
moc_qglDisplay.cpp*
-rwxr-xr-x+ 1 glenn.coombs Domain Users  6493 Apr 25 15:04
moc_qglMultiWindow.cpp*
-rwxr-xr-x+ 1 glenn.coombs Domain Users  2529 Apr 25 15:04
moc_qglWindow.cpp*
-rwxr-xr-x+ 1 glenn.coombs Domain Users  4242 Apr 25 15:04
moc_videoGeneric.cpp*
-rwxr-xr-x+ 1 glenn.coombs Domain Users  8513 Apr 26 08:27
../ctrlMenu/ctrlBasic.cpp*
-rwxr-xr-x+ 1 glenn.coombs Domain Users  1237 Apr 26 08:28
../ctrlMenu/ctrlBasic.h*

I would expect the moc_ctrlBasic.cpp file to be regenerated but it isn't.
In fact, if I manually delete moc_ctrlBasic.cpp then the build fails:

1>------ Build started: Project: yuv_player, Configuration: Debug Win32
------
1>  yuv_player_automoc.cpp
1>yuv_player_automoc.cpp(2): fatal error C1083: Cannot open include file:
'moc_ctrlBasic.cpp': No such file or directory

The only way to get moc_ctrlBasic.cpp regenerated that I have found so far
is to manually delete both it and yuv_player_automoc.cpp.
