----------------------------+---------------------------------
 The lintian QA tool reported several pkg-config-references-unknown-shared-
 library issues:

  * usr/share/pkgconfig/grass.pc -lgrass_gmath
  * usr/share/pkgconfig/grass.pc -lgrass_gis
  * usr/share/pkgconfig/grass.pc -lgrass_datetime
  * usr/share/pkgconfig/grass.pc -lgrass_gproj
  * usr/share/pkgconfig/grass.pc -lgrass_raster
  * usr/share/pkgconfig/grass.pc -lgrass_vector
  * usr/share/pkgconfig/grass.pc -lgrass_dbmibase
  * usr/share/pkgconfig/grass.pc -lgrass_dbmiclient
  * usr/share/pkgconfig/grass.pc -lz
  * usr/share/pkgconfig/grass76.pc -lgrass_gmath
  * usr/share/pkgconfig/grass76.pc -lgrass_gis
  * usr/share/pkgconfig/grass76.pc -lgrass_datetime
  * usr/share/pkgconfig/grass76.pc -lgrass_gproj
  * usr/share/pkgconfig/grass76.pc -lgrass_raster
  * usr/share/pkgconfig/grass76.pc -lgrass_vector
  * usr/share/pkgconfig/grass76.pc -lgrass_dbmibase
  * usr/share/pkgconfig/grass76.pc -lgrass_dbmiclient
  * usr/share/pkgconfig/grass76.pc -lz

 The tag description is as follows:

 {{{
    The specified pkg-config(1) file references a shared object via, for
    example, Libs: -lfoo but this package appears to not ship the
    associated "libfoo.so" shared library.

    This will result in a linker error and was likely caused by a missing
    installation step.

    Please ensure that your package ships the corresponding libfoo.so
    shared object file.

    Refer to the pkg-config(1) manual page and
    https://bugs.debian.org/919180 for details.
 }}}

 Part of the problem is that the libraries are in a private directory like:
 {{{
 ./usr/lib/grass76/lib/libgrass_gmath.7.6.so
 ./usr/lib/grass76/lib/libgrass_gmath.so -> libgrass_gmath.7.6.so
 }}}
 And not having the .so symlink provided by the grass-dev package like for
 normal shared library packages.

 Another issue is that `-lm` & `-lz` should probably be moved from `Libs:`
 to `Libs.private:`.
