[gdal-dev] Building GDAL 3.0.0 with Proj 6.0.0

[Jim Klassen]

Did you set ./configure --with-proj=${INSTALL_DIR}?

Where INSTALL_DIR is the install directory (prefix) of proj/gdal.

I also had to set:

export LDFLAGS="-L${INSTALL_DIR}/lib -Wl,-rpath,${INSTALL_DIR}/lib"

to get gdal to actually link against the new proj (vs the system 
installed one).
