compile gdal with ESRI FileGDB_API Ubuntu

I’m trying to build GDAL on Ubuntu 16.04 with ESRI FileGDB_API driver support. I’ve followed the instructions here: https://trac.osgeo.org/gdal/wiki/FileGDB and have attempted to pass the location of proj included with the ESRI FileGDB_API. Here is my configure command:

./configure --with-static-proj=/usr/local/FileGDB_API/lib/libFileGDBAPI.so --with-fgdb=/usr/local/FileGDB_API

And the error:

configure: error: --without-static-proj and --with-fgdb are both available. There might be some incompatibility between system libproj and the embedded copy within libFileGDBAPI

I get the same error if I remove --with-static-proj and if I use --without-static-proj.

I’m attempting to compile gdal 2.3.1 and I’m using the FileGDB_API version 1.5 for gcc 5.1.

./configure --with-static-proj4 --with-fgdb=/usr/local/path
