Sf: macOS install instructions

[pat-s]

I am able to install {sf} 0.9-3 from source on macOS without the need for custom configure.args.

With

• proj 7.0.1
• gdal 2.4.4_6
• geos 3.8.1_1

on R 4.0.0 on latest macOS 10.15.4

proj, gdal and geos installed (and linked) via brew. No custom Makevars set.
Might be worth updating the install instructions in the README?

If you use PROJ >= 6, you should also use GDAL >= 3. It doesn't make sense to go beyond PROJ 5 for GDAL 2, which doesn't bring the benefits of the GDAL barn-raising project.

[pat-s]

User relying on homebrew-core on macOS do not have a version choice here.

One could use the osgeo4mac tap which comes with osgeo-gdal and osgeo-proj but robustness and maintenance of these formulas vary over time (judging from my personal experience and talking to the devs).

If you use PROJ >= 6, you should also use GDAL >= 3.

This could go into the README as a separate info. This PR just addresses the fact that configure.args is not (anymore) needed for installing {sf}.

In the not so far future, homebrew core will also update to gdal 3 anyways.

[ateucher]

That's good to hear @pat-s, thanks for the update. I agree - the osgeo4mac tap, while in principle seems like a great idea, has been pretty unreliable and I've stopped using it.

Gdal was just updated to 3.1 on Homebrew, so I just installed sf from source.
I had to adjust the install.packages() call to use type = "source" to actually compile it. Using the command from the install instructions didn't trigger a source installation.
In a addition I had to change the path to proj.

The working call for me:

install.packages("sf", configure.args = "--with-proj-lib=/usr/local/Cellar/proj", type = "source")

Which results in sf linking to GEOS 3.8.1, GDAL 3.1.0, PROJ 7.0.1

I'll admit that I'm not sure if I at some point made changes to where homebrew install stuff since my system apparently refers to /usr/local/Cellar/ and not /usr/local/lib/. So that part might needs to remain as is, but I believe that the type argument needs to be set to "source" in the instructions.

MacOS 10.14.6, R 4.0.1

[ateucher]

As I mentioned in #1430, I also installed sf from source using homebrew core gdal/proj/geos (not the osgeo tap), and didn't need an --configure.args etc. Just install.packages("sf", type = "source")

[pat-s]

@ateucher
This works for quite some time already, I think since proj 7.0.1 arrived in homebrew-core.
AFAIK the workaround was needed for PROJ 7.0.0.

GDAL2 was never (?) an issue in {sf}.

[ateucher]

You're right @pat-s - I was just responding to to @LDalby to say that it's not necessary to specify --configure.args (as you say, since PROJ 7.0.1).
