From: Arne Schwabe <[email protected]>
Users seem to struggle to read the full error message. This adds an
indication if pkg-config is actually found to the warning/error message
that use pkg-config.
When found:
configure: error: libnl-genl-3.0 package not found or too old. Is the
development package and pkg-config (using /usr/bin/pkg-config) installed? Must
be version 3.4.0 or newer for DCO
not found:
configure: error: libnl-genl-3.0 package not found or too old. Is the
development package and pkg-config (not found) installed? Must be version 3.4.0
or newer for DCO
