Re: [CMake] Strange options for Sun Studio compiler

[Doug Henry]

Before I commit anything, I would like to verify how cmake is doing its compiler detection.  Is everything simply based on name?  I can have cc in my path which is gcc, or I can set my path in a way that has cc from sun studio.  Is cmake capable of telling the difference?  I have a problem where I could have f77 from either set of compilers but each requires different compiler options.  Can this be done using cmake?

Please include this in your Linux-CC.cmake that you post to the feature
request I mentioned in the other response.  Since no one has used this
compiler before I don't mind including the option until someone
complains their version doesn't have it.

Thanks,
