setup.py for Python bindings doesn't work for virtualenv
|Reported by:||hobu||Owned by:||hobu|
virtualenv and pip use the source code of the bindings on PyPI for installation, and these have a setup.cfg installed with them that points at ../../apps/gdal-config
When this is run the first time, it fails, and the bindings installation cannot happen. We should attempt to simply run a gdal-config that exists on the path one time in addition to what was specified to setup.cfg.
