# The following tests assume that the atf-c.pc file is installed in a
# directory that is known by pkg-config.  Otherwise they will fail,
# and you will be required to adjust PKG_CONFIG_PATH accordingly.
#
# It would be possible to bypass this requirement by setting the path
# explicitly during the tests, but then this would not do a real check
# to ensure that the installation is working.
