Load configuration from a set of predefined files. * * If the environment variable (or configuration option) GDAL_CONFIG_FILE is * set, then CPLLoadConfigOptionsFromFile() will be called with the value of * this configuration option as the file location. * * Otherwise, for Unix builds, CPLLoadConfigOptionsFromFile() will be called * with ${sysconfdir}/gdal/gdalrc first where ${sysconfdir} e
