# exit code 0 if the package exists; 1 if it does not, with no Standard
# Output.  But we have evidence that on one system, it issues the whole
# package not found try a different path, blah, blah, blah message that
# looks like a failure in the build.  We're hoping --exists does not do that.
# But maybe we didn't do --exists in the first place because it doesn't exist
# on older pkg-config.  19.09.20.
#
# Note that --exists is better for another reason - it fails when the named
# package exists, but it is unusable because its prerequisite packages don't.

# Also note that in both cases, the shell command fails if pkg-config
