I don't know much about configure, are those tests bash compatible?
If so I would guess the above is testing for whatever
"--with-proj-includes=" was set to. This is not auto-detected; if the
includes and libs are in standard paths /usr/include, ld.so.conf,
the conftests will work without that being set.
So the above just checks to see if you set --with-proj-includes and
arbitrarily starts setting a epsg path based on that. :/
better: (if it works)
# Define share/proj/ directory for epsg code file
if test -n "$PROJINC"; then
for testdir in /usr /usr/local ; do
if test -d $testdir/share/proj ; then
"$PROJINC/../share/proj" could be better evaluated? use $PROJLIB ?
where does epsg get stored on a Mac, Cygwin, windows native, etc?
how does PROJ4 know where to find it if PROJ_LIB isn't set?
