Thought to share a build experience with PROJ.6 6.1.0 on macOS
Mojave (10.14) natively. A change in "configure" was required. I
also passed extra variables to "configure". Let's call this a
sanity check ahead of a bug report? Soonest I can generate diffs
is at then end of this week.
In "configure" the test for the presence/absence of SQLite3 seems
to always fail. In other words, absent pkgsrc, regardless of
whether SQLITE3_CFLAGS and SQLITE3_LIBS are defined or not, the
results are the same. I have not, yet, installed pkgsrc.
To successfully compile, I also had to tease the right results
out of configure. Notably, I pointed to SQLite3 twice.
