# - determine variables defined in pkg-config files
#
# Usage:
# pkg_check_variable(<PKG_NAME> <VARIABLE_NAME>)
#
# Checks for a variable in the given package and translates to a call such as
# `pkg-config --variable=<VARIABLE_NAME> <PKG_NAME>`. The output is a cached
# variable named
#
# <PKG_NAME>_<VARIABLE_NAME>
#
# Note that both names are uppercased and any dashes replaced by underscores.
