# Package-settable variables:

# PKGCONFIG_OVERRIDE
# The list of pkg-config files relative to WRKSRC in which the
# compiler flags need to be adjusted.
#
# PKGCONFIG_OVERRIDE_STAGE
# The stage in which the pkg-config files will be adjusted. By
# default, this is pre-configure.

### pkg-config-override inserts the compiler's "rpath" flag into
### pkg-config data files so that ``pkg-config --ldflags <module>'' will
### return the full set of compiler flags needed to find libraries at
### run-time.
