I took this approach, and it seems to work fine.

I've now also tested with MSVC and MinGW on Windows. I couldn't seem to get 
cmake to work on cygwin though.

I'll see if I can test on Mac too before pushing to the cmake repo. 

One question I have is: Will the unit tests for this be run on all platforms 
before it gets to master? I suspect there may be breakage on systems I have 
no access to, such as SunCC.

Cool, I have push access now, so I'll review the workflow later.

Thanks,
