[postgis-devel] Using pkg-config for PROJ

Mine are. Also Docker is building several dependencies from source and it
doesn't seem to have issues. OTOH, Postgis' defaults are pretty
much?tailored just for Linux.

There is an easy way to check:
pkg-config --libs proj (or whatever other project)
pkg-config --cflags proj

With pkg-config there is a way to pass the flags (env variables PROJ_CFLAGS
and PROJ_LDFLAGS) and in that case the default will be ignored. This is
both why I don't get why Postgis has its own way to do it and why, if we
want to keep having manual as default, it's not worth it to force
pkg-config being mandatory ( and simply check pkg-config if it's installed).
