In my project I build on Linux i686 and I use a Toolchain file to
specify the ARM cross-compiler
https://cmake.org/cmake/help/v3.6/manual/cmake-toolchains.7.html
The nice thing is that if you mark some files as "generated" CMAKE will
automatically use the build rather than the target toolchains. For
instance, I have a Flex/Byson compiler that is generated locally on i686
, but then compiled for ARM.

Michele

Thanks Craig,
Your solution will work for me I think.

Here's one possible solution (not perfect, but has been working in
production for us for a while now for a similar scenario to what you
describe):
http://stackoverflow.com/q/36084785/1938798
An alternative is a superbuild arrangement which would require a top
level project to drive two sub-builds brought in via ExternalProject
<https://cmake.org/cmake/help/latest/module/ExternalProject.html>, one
for the host and the other for arm. This is both better and worse,
depending on your point of view, so you may need to do some
research/experimenting to see which is a better fit for your situation.

Hi all,
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 :)
Regards
/Robert
