 Priority:  normal          |  Milestone:  7.2.3
Component:  Default         |    Version:  7.2.2

----------------------------+-------------------------
 GRASS is claimed to be using the GEOS C API instead of the unstable C++
 API according to:

  https://trac.osgeo.org/geos/wiki/Applications

 `configure.in` checks for `geos_c.h`, but uses `geos-config --libs`
 instead of `geos-config --clibs` causing linking to `libgeos-<VERSION>.so`
 in addition to `libgeos_c.so`.

 The attached patch updates the `geos-config` command to use `--clibs`.
