This isn’t an issue with other projects besides PostGIS that use GEOS?

Perhaps related, how much trouble would it be to get PostGIS to use pkgconfig 
for GEOS.  I see that GEOS does ship pkgconfig files.

 

It’s always annoying when I try to do it that I have to explicitly specify the 
geos-config file in PostGIS when in other cases, we can read the pkg-config and 
have in fact standardized on that for other dependencies we use.

 

I’ve added PostGIS dev to this since well we seem to be talking about PostGIS 
now.

I’m on both sides of the argument now. The best/better practice might be to 
leave the install behaviour as-is and try to coerce PostGIS into ensuring the 
LD_RPATH on postgis.so, and other targets is set to the discovered locations of 
the dylib files in the ./configure.

I’ll hold off on releasing until there is consensus on this issue.

I have committed this into main, and would like to pull it back a few stable 
braches too, since I need it to effectively work on postgis/geos on my Macbook, 
but I am going to hold off on the stable branches for a while, if anyone 
working on main finds that this change has broken something in *their* 
environment, please let me know.
