No, but files with extensions like ".txt" that do not mean anything to 
CMake or Visual Studio can be included in the project file with no ill 
effects.  We can add a source file property to cause this behavior:

SET_SOURCE_FILES_PROPERTIES(foo.xyz PROPERTIES EXCLUDE_FROM_BUILD 1)

Please add this as a feature request here:
