[CMake] Building a MS COM Dll with Cmake

[Steven Velez]

Since no one has yet replied, I will comment that this workflow is
much like what Qt does with the moc (meta-object-compiler) and uic
tools.  Looking at the FindQt4.cmake and the referenced
Qt4Macros.cmake  files, it seems like these could provide some
examples to follow...

... though its true they are not structured for instruction.
