 ### Troubleshooting
 
 - Ubuntu 18.04 users will not have a working emulated Wii Remote cursor. To fix this, install `gcc-11` from [this PPA](https://launchpad.net/~ubuntu-toolchain-r/+archive/ubuntu/test) and instead of `cmake ..` type `cmake .. -DCMAKE_C_COMPILER=gcc-11 -DCMAKE_CXX_COMPILER=g++-11` during the build process. This may become necessary in the in the long term anyway to solve issues for anyone still building on 18.04 in the future.
