[CMake] Fwd: ADD_CUSTOM_COMMAND and Visual Studio 2010

[elizabeta petreska]

If I use Visual Studio 2005 generator everything works well.

But, it seems that Visual Studio 2005 does not require the input file ( in
this case foo.txt.rule ) to Custom Build Step to exist on disk. So the
Visual Studio 2005 generator never makes foo.txt.rule to the disk, but the
whole thing still works.

While in Visual Studio 2010 it seems that the input file to custom build
step must exist on disk.

I tested this with defining Custom Build Steps directly through The Visual
Studio 2005 and Visual studio 2010 IDE.

So , someone can say is this a bug in the Visual Studio 2010 generator?

thank you
