Sorry there was a typo in my previous email. PKG_CONFIG_PATH has to be
set to the location of "libcurl.pc", which is inside lib/pkgconfig. So
the full code is this:

   brew install curl-openssl pkgconfig
   curl -OL https://github.com/curl/curl/raw/master/docs/examples/crawler.c
   export PKG_CONFIG_PATH="/usr/local/opt/curl-openssl/lib/pkgconfig"
   cc -o crawler crawler.c $(pkg-config --cflags --libs libxml-2.0 libcurl)

Use otool -L to confirm that executable links against the correct
libcurl shared library:

  otool -L crawler

# crawler:
# /usr/lib/libxml2.2.dylib (compatibility version 10.0.0, current
version 10.9.0)
# /usr/local/opt/curl-openssl/lib/libcurl.4.dylib (compatibility
version 11.0.0, current version 11.0.0)
# /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current
version 1252.250.1)
