I know I am late to the party, but I ran into the same thing today
(Building Proj 6, GDAL 3 on Debian Stretch). I got around it by
setting LDFLAGS before running ./configure so the linker finds the
proj 6 install first. Without setting LDFLAGS, ./configure would
find the new proj, but libtool would try to link to the system one
(by full path no less, not just -lproj).<br>
<br>
So assuming proj 6 (and GDAL) is installed in $INSTALL_DIR:<br>
<br>
export LDFLAGS="-L${INSTALL_DIR}/lib -Wl,-rpath,${INSTALL_DIR}/lib"<br>
./configure \<br>
--prefix="${INSTALL_DIR}" \<br>
--with-proj="${INSTALL_DIR}" <br>
<br>
I'm not sure if it matters, but I also set
CMAKE_INSTALL_RPATH=$INSTALL_DIR when I build proj.<br>

Look at the output of<br>
<br>
ldd
/home/simon.eves/scratch/gdal3/gdal-3.0.0/.libs/libgdal.so
| grep proj<br>
<br>
It should normally point to the libproj.so.15 of<br>
