[CMake] different assemblers in single build?

[Yuri Timenkov]

Hi,

You should have either 2 build trees or use custom commands.
If you have a lot of files you should go first way.
To ease development you may compile other tree using external project.
Unfortunately external project is not rebuilt if its sources changed. You
have to do it manually.
