[CMake] MSVC++ IDE is licensed but CMAKE build appears to fail to pick up licence from command line

[Asterion Daedalus]

I have found an problem that appears in two open source projects I downloaded.  Both appear to balk because of a missing or expired VC++ licence.  This is despite the fact that the IDE is running with a licence.
MSN "help" simply claims it is a bug in CMAKE so I feel that I will be ping-ponging.  
Has anyone else come across, or more importantly solved the problem?  I am trying a re-install of MS VC++ at this moment as I am assuming it is the culprit because two CMAKE makes, from different authors, are having the same problem.
