Yes, there is, see Modules/CMakeForceCompiler.cmake.
But the better option is to make the compiler known to cmake.
Please have a look at Modules/CMakeCCompilerId.c.in . 
Is there a similar test we can use for the Dignus compiler ?

The name of the operating system is now "ZOS", so CMake looks in 
Modules/Platform/ for a file ZOS.cmake and doesn't find it.
So you have to create one. I don't know much about z/OS. E.g FreeBSD.cmake is 
very small, maybe you can start from that if it's more or less similar.
