Yes. You need to duse two different assembler "dialects", each "dialect" counts as a separate language to cmake, so you can have many in parallel. So you should add e.g. a ASM-DSP dialect, and set the language of the source files to ASM-DSP. This this assembler will be invoked on these files. Adding an assembler dialect is not hard, you need just a few tiny files: http://www.cmake.org/Wiki/CMake/Assembler This page is slightly out of date, but the documentation how to add a new assembler is still valid. Just have a look at the Modules/ directory for the ASM-related files, you should see how this works. Alex
