I'm trying to install the curl package in R-3.5.1. I am on Mac OSX 10.13.6 and using Homebrew as my package manager. E.g.
> install.packages("curl")
Installing package into ‘/Users/user/.R/3.5.1-lib’

Found pkg-config cflags and libs!
Using PKG_CFLAGS=
Using PKG_LIBS=-lcurl
------------------------- ANTICONF ERROR ---------------------------
Configuration failed because libcurl was not found. Try installing:
* deb: libcurl4-openssl-dev (Debian, Ubuntu, etc)
* rpm: libcurl-devel (Fedora, CentOS, RHEL)
* csw: libcurl_dev (Solaris)
If libcurl is already installed, check that 'pkg-config' is in your
PATH and PKG_CONFIG_PATH contains a libcurl.pc file. If pkg-config
is unavailable you can set INCLUDE_DIR and LIB_DIR manually via:
R CMD INSTALL --configure-vars='INCLUDE_DIR=... LIB_DIR=...'

Following their suggestions, I have libcurl in a reasonable system level directory, /usr/lib, i.e.
$ find /usr/ -name "*libcurl*" -print

I have pkg-config, i.e.
$ which pkg-config
/usr/local/bin/pkg-config
I also have set PKG_CONFIG_PATH, i.e.
$ echo $PKG_CONFIG_PATH
/usr//local/Homebrew/Library/Homebrew/os/mac/pkgconfig/
I have also tried the suggestion setting INCLUDE_DIR and LIB_DIR directly, i.e.
$ R CMD INSTALL --configure-vars='INCLUDE_DIR=/usr/include/curl/ LIB_DIR=/usr/lib' curl

Warning: invalid package ‘curl’
Error: ERROR: no packages specified
I am at a complete loss here. I'm not as familiar with developing on OSX, so maybe I'm missing something here. Looking back at a previous install of R-3.4.2, it seems that I didn't have difficulties installing this package previously.
QUESTION: How do I get the curl package installed? This question seems to be related, but is for Linux.
