Can you build cmake from this branch I just created ?
http://cmake.org/gitweb?p=stage/cmake.git;a=shortlog;h=refs/heads/TI_DSP_Compiler

It has basic support for the TI compiler, see the files 
Modules/Compiler/TI_DSP-*.cmake.

At least I was able to compile and link C, C++ and an assembler file.

It should also work to copy these three files simply in the Modules/Compiler/ 
directory of your installed cmake, but you need at least CMake 2.8.4.

I'm quite sure these files are not complete.
Please give them a try and I'd be happy about patches to make them really 
work.
