I've installed GDAL2.3dev on my mac using Homebrew, expecting it to support GeoPDFs already. But when I run
gdalinfo on a pdf file from USGS, I still get this error:
ERROR 4: `WA_Sunrise_244132_1971_24000_geo.pdf' not recognized as a supported file format.
What do I need to do add PDF support to GDAL?
