CMake detecting system toolchain

Verification

Introduce the issue

When generating the project, CMake claims the compiler in use is one from the system, not the arm crosscompiler. I don't know if this causes side-effects, but it seems incorrect nonetheless.

Output from a build workflow.

-- The CXX compiler identification is GNU 11.3.0

Preferred solution

Moving the inclusion of the toolchain file earlier seems to fix the issue, but I'm not very familiar with CMake, so I want to give an opportunity to someone who knows better to look at it and find a good solution to this issue. This can be an opportunity to also check the structure of the CMake files, which seems like it might be quite outdated.

No response

Start by inspecting the CMake files and the toolchain file, then reproduce project generation from the build workflow that reports /usr/bin/cc and /usr/bin/c++. Check when the toolchain file is included relative to compiler detection. Done means CMake identifies and uses the ARM crosscompiler instead of the system compiler, with the workflow output confirming the change.
