[Cmake] VS run-time library selection

[SMITH,GORDON (HP-FtCollins,ex1)]

Hello -

I have a small difficulty in Visual Studio linking a library I've created
using third party object files (no source). The object files (apparently)
link against the single threaded runtime library. The default "code
generation" setting in cmake generated projects seems to be to link against
the multithreaded library. This creates conflicts in this case.

Is there a good way to change the run-time library setting from cmake?

   Thanks,
