PROJ/travis/linux_gcc7, branch 6.1.0 Forked from https://github.com/OSGeo/PROJ autoconf build: add a PROJ_DB_CACHE_DIR trick to speed-up builds 2019-04-28T20:09:03+00:00 Even Rouault even.rouault@spatialys.com 2019-04-28T20:01:40+00:00 7bf0f597b8b0d7d209d856fa106b521ed65678af If the PROJ_DB_CACHE_DIR environment variable is defined, then a $(PROJ_DB_CACHED_DIR)/proj.db.sql.md5 file is used to determine if the set of .sql files has changed since the last time. If not then $(PROJ_DB_CACHED_DIR)/proj.db is directly used. This can saved a few seconds when doing rebuilds. This is a poor man equivalent of ccache for generating the database :-)
