It is probably possible, but it's a hack. In general, you can only have one compiler per language in one cmake build tree. Among other because the results of configure checks are compiler-specific, and they are saved in the global cache, so you can't have multiple correct values. What can be done, is to change the CMAKE_C_COMPILER etc. variables in a subdir, then those changed settings will be used there. If you use additional stuff like find_package() etc. you must be sure you know what you are doing, so that it doesn't conflict with other (global) cache variables in your project.
