For instance, I have a Flex/Byson compiler that is generated locally on i686 , but then compiled for ARM.

<br>
I am crosscompiling a project for arm (on linux i686), and use codegeneration tools within the project (together with add_custom_command). Of course, this will fail, since the tools are compiled for arm also and thus won't execute on my host system. So the
tools need to be compiled for i686 whilst the rest for arm. I'm sure this can be handled by CMake although haven't done it before so would appreciate pointers :)<br>
