Comment (by robe):

 My pkg_config_path looks like this:


 {{{
  /projects/sqlite/rel-
 sqlite3w64/lib/pkgconfig:/projects/protobuf/rel-3.2.0w64/lib/pkgconfig:/projects/json-c/rel-0.16w64/lib/pkgconfig:/projects/proj
 /rel-
 proj-9.8.1w64/lib/pkgconfig:/projects/gdal/rel-3.13.1w64/lib/pkgconfig:/projects/zlib
 /rel-
 zlib-1.2.13w64/lib/pkgconfig:/projects/gtkw64/lib/pkgconfig:/mingw/x86_64-w64-mingw32/lib/pkgconfig

 }}}

 and /projects/proj/rel-proj-9.8.1w64/lib/pkgconfig is the config folder
 for my proj.  I did have to fix paths in the proj.pc which I also did for
 the 8.2.1 but that did not fix the issue.
