Use user provided lib/irrlichtmt if available (#11276)
Use user provided lib/irrlichtmt if available Make it possible for a user to provide the IrrlichtMt dependency as subdirectory at `lib/irrlichtmt`. The subdirectory is added with the `EXCLUDE_FROM_ALL` flag to prevent `libirrlichtmt.a` or other header files to be installed. This enables the user to do the following to satisfy the IrrlichtMt dependency: git clone --depth 1 https://github.com/minetest/irrlicht.git lib/irrlichtmt cmake . -DRUN_IN_PLACE=TRUE
