# Download CEF and install a shared copy of it and its wrapper at $PREFIX/cef$cefbranch
# Usage:
#   [PREFIX=...][DESTDIR=...] sh buildwrapper.sh [branch]
#
# Directory layout:
# $PREFIX/cef$cefbranch
#   include
#   Release
#    lib
#    cefclient
#
# Tip for normal users: create directory $PREFIX/cef$cefbranch as current user beforehand to avoid need for root
# Tip for packagers: set $DESTDIR to the staging area
#
# Requires something like 'sudo apt install cmake ninja wget build-essential'
