[CMake] ADD_CUSTOM_COMMAND issues

[Brandon Van Every]

I reproduce the lack of COMMENT.  My system is CMake 2.4.6, Windows
2000 SP4, MinGW generator, mingw32-make executed from a Windows
command prompt.  This is a bug.  Please file it in the bug tracker,
I'd say priority "3 - Medium".  Feel free to cut-n-paste my
confirmation.

C:\devel\mingw\append>mingw32-make
[100%] Building C object CMakeFiles/test.dir/test.obj
Linking C executable test.exe
[100%] Built target test

The WORKING_DIRECTORY works fine.  It is set to use the SOURCE dir,
and that's where the \tags directory appears.  Of course it would be
better CMake style to have it in the BINARY dir, to support
out-of-source builds.

C:\devel\src\append>dir
 Volume in drive C has no label.
 Volume Serial Number is 08F5-AEDA

 Directory of C:\devel\src\append

               2 File(s)            323 bytes
               3 Dir(s)     853,618,688 bytes free


Next question is whether the COMMENT bug is present in CVS.  I don't
have time to check right now.

Cheers,
Brandon Van Every
