A possible fix it to re-write

mujoco-feedstock/recipe/disable_copy_cxx_files_in_python_package.patch

Line 38 in 6b13f53

+ _MJ_INSTALL_DIR = os.path.join(os.environ.get('CONDA_PREFIX'), 'Library')

to actually encode the relative path between the python files and the C++ headers and plugin, it should not be too difficult.
