Matt,

By default GDAL is built to try and dynamically load libproj.so at runtime.
The good part of this is that you don't need to have libproj around to build
GDAL, but if you later install it - bam - GDAL's projection support starts
working too.

You can try building and installing PROJ now and see if things work, but
this stuff may be fragile on Cygwin.

Best regards,
