#3707: Protobuf configure may need more work
---------------------+---------------------------
 Reporter:  robe     |      Owner:  pramsey
     Type:  defect   |     Status:  new
 Priority:  high     |  Milestone:  PostGIS 2.4.0
Component:  postgis  |    Version:  trunk
 Keywords:           |
---------------------+---------------------------
 As noted in #3661, at least building under mingw, it was not sufficient to
 specify the --with-protobufdir directory path.

 I tried all sorts of permutations to figure out what's required if you are
 installing in non-standard place.

 It seems I had to do all the following:

 1) Specify the --with-protobufdir (without this if I had protobuf and
 protobufc in my path, it would pass configure, but fail at compilation
 with can't find include.  Though I realized now if I include include in my
 path that might have done the trick.

 2) Configure failed at finding PROTOBUFC, unless I also

 had:

 export PKG_CONFIG_PATH=path/to/protobuf/lib/pkgconfig

 3) Tried as I did, I couldn't get it to work if I had protobuf and
 protobufc installed in separate directories.

 This could all be user error, but at lease probably should be documented
 so people needing to build from source and not wanting to install in
 default locations (e.g. cause they are packagers)  don't run thru all this
 nonsense.
