Matt,

I've changed the way autoconf detects openjpeg in GDAL trunk. It now requires the pkg-
config info to be available.
Normally pkg-config should be able to find the info even with the /usr/local installation prefix

At least, that works on our Travis-CI platforms such as
ci/travis/precise_clang/before_install.sh
ci/travis/precise_clang/install.sh

You may try running GDAL configure with
PKG_CONFIG_PATH=/usr/local/lib/pkgconfig set as env variable, in case that helps (which I 
doubt is needed)

Perhaps add a ldconfig after make install of openjpeg ?

You may have a look at config.log generated by GDAL configure to help debugging the issue.

For GDAL 2.2.2, the symlink trick should work too.
