When building with MSVC, some libraries had PROGRAM_NAME set to "Mixbus" and PROGRAM_VERSION set to "3". Whereas other libraries had PROGRAM_NAME set to "Mixbus3" while PROGRAM_VERSION was an empty string.
I've a horrible feeling there must have been a reason for this but I can't quite think what it was. Hopefully though, this change will standardize everything.
These are trivial (no-op) fudges - to ensure that if we can't copy the built executable for whatever reason, it won't get flagged up as a build failure.
