Comment 4 for bug 1161064

Full example of how to compile external clients:

1. If mir was not installed to a system directory, but locally, you will need to set:
  export PKG_CONFIG_PATH=$mirdir/lib/pkgconfig

2. gcc -std=c99 -o demo demo_client.c `pkg-config mirclient --cflags --libs`

This works right now. So bug invalid.
