Interesting.
And the input files for the xgate compiler are also plain C  files ?

In general, using different compilers for the same language is not supported 
by cmake, or using compilers for different architectures within one build 
tree.

You can probably work around that by defining your xgate-input files as a 
different language. If they have the same extension (i.e. .c) I think you can 
use set_source_files_properties() to override the language of a source file.

<hack>
Since you don't have support for C++ in your projects, maybe you could define 
the C++ support for the xgate compiler ?
I.e. set up the CXX variables so that they work for the xgate stuff, and mark 
the xgate input files via set_source_files_properties() to CXX ?

Would have to check... 
I think you'll see when you try :-)
What do you need it for ?
