[CMake] User generated header file

[Perry Ismangil]

I'm converting Visual Studio project files to CMake.

On of our project, one of the header file included in the project is
deliberately missing, the user have to manually create it before
building for the first time.

When I tried this with cmake, it complained that it couldn't find the
header file specified, which is of course true.

How do I suppress this behaviour?

Thank you.

Best Regards,
