Disclaimer: I have no experience with MinGW.

The error is : Fatal error: can't write 66 bytes to section .text of _deps/qaterial-build/CMakeFiles/Qaterial.dir/Unity/unity_1_cxx.cxx.obj: 'file too big'

You could try to disable unity build with cmake -DQATERIAL_ENABLE_UNITY_BUILD=OFF.

I don't have the environment to replicate but the fix should be something like:

if (MINGW)
   target_compile_options(Qaterial PRIVATE "-Wa,-mbig-obj")
 endif()

Tell me if this work, you can open a PR to fix it if you can replicate the error in the CI. Otherwise I do not wish to support what we don't have CI env for.

Have a nice day
