Usage: ./installdeps [TARGET]
Try to install the dependencies needed for this project appropriately on the
host OS.

This program may require sudo.

A cross-compile target may be specified as the only parameter, of either
mingw-w64-i686 or mingw-w64-x86_64. This is only supported on Arch Linux.

OPn MSYS2 dependencies are installed for both 32 and 64 bit native Windows
targets implicitly.

  -h, --help, --usage                Show this help screen and exit.

Examples:
  ./installdeps                        # install dependencies for a host build
  ./installdeps mingw-w64-i686         # cross-compile for 32 bit windows (Arch Linux only)
