Different cross-compilers for different subdirs?

[nils-werner]

Hey all, I have an embedded project where parts of it are compiled using arm-linux-gnueabihf-gcc and other parts are compiled using arm-none-eabi-gcc. So far I've migrated all the Linux-parts to Meson and it's working great! However with the bare-metal parts I am now clueless how I would include them in my build definitions...

It seems that Meson assumes/requires the same compiler for the entire project, is that right? So how would it be possible to architecture such a project in Meson?
