Regarding your idea to use the output of "cl /?" to determine the version number, I think it is a good one. If you have time to rewrite the module to do this instead and test it I would merge the changes for a future version of CMake. Some potential issues. 1. "cl /?" appears to pause waiting for input, this would have to be mitigated somehow in a safe way or perhaps just "cl" could be executed as that appears to include the output. 2. "cl" or "cl /?" output would have to be verified on VS8 to ensure it outputs there as well (it appears to be there in VS9/Express) 3. You couldn't just run "cl", you would have to find out the CMake variable for the compiler and run that. My time is really limited. If you're interested, please create a new ticket and submit a patch. It would save probably at least a second off of an initial configure. -- Philip Lowman
