Building Weston on Ubuntu 16.04

The following sequence of commands successfully built Weston and XWayland on a pristine Ubuntu 16.04 system, on August 16, 2016. These commands will probably work on any system based on Ubuntu 16.04. ~2 GB used with documentation dependencies, ~500 MB used without them.

All the "apt install" commands can probably be replaced by just running "sudo apt build-dep wayland weston wayland-protocols libinput xserver-xorg".

"make check" runs included tests, and is not required, but is a good habit.

For errors like "No package 'libffi' found" you can try searching with "apt-file search /libffi.pc". 'pc' stands for pkg-config.

# setup environment for local install:
export WLD=$HOME/install
export LD_LIBRARY_PATH=$WLD/lib
export PKG_CONFIG_PATH=$WLD/lib/pkgconfig/:$WLD/share/pkgconfig/
export PATH=$WLD/bin:$PATH
export ACLOCAL_PATH=$WLD/share/aclocal
export ACLOCAL="aclocal -I $ACLOCAL_PATH"
mkdir -p $ACLOCAL_PATH
export MAKEFLAGS="j5" # run 5 threads, or use your own flags
