On Raspberry Pi:

1. Install the required development files (headers and libraries) for compilation. These will later be used on the host PC.
2. Create the Qt library target directory and give the pi user permission to modify files in the folder. This allows rsync to copy the library back to the Pi.

On Host PC:

1. Create a working directory and download the Raspberry Pi cross compilation toolchain.
2. Create a folder to contain copies of Pi's development files required for cross compilation.
3. Copy the development files.
4. Fix symlinks.
5. Download Qt source code and configure.
6. Build and install to the qt5pi folder.
7. Copy Qt library to Pi.
