tl;dr: I think I need guidance on how to specify <LIBPATH> in

perl Makefile.PL --with-libidn=<LIBPATH> --with-libidn-inc=<INCPATH>

Additional details:

Building Net::LibIDN using

perl Makefile.PL --with-libidn=/usr/local/lib --with-libidn-inc=/usr/local/include

yields the following error

ld: library not found for -lidn
clang: error: linker command failed with exit code 1 (use -v to see in
+vocation)
ld: library not found for -lidn
clang: error: linker command failed with exit code 1 (use -v to see in
+vocation)
This module requires GNU Libidn, which could not be found.

However, I do have GNU Libidn2 installed as follows

/usr/local/lib/libidn2.0.dylib
/usr/local/lib/libidn2.a
/usr/local/lib/libidn2.dylib
/usr/local/lib/libidn2.la

/usr/local/include/idna.h -> /usr/local/include/idn2.h
/usr/local/include/idn2.h

For context, I ran into the same problem as this StackOverflower except I'm on macOS 10.14 Mojave and was able to make my way past

__test1.c:1:10: fatal error: 'idna.h' file not found
#include <idna.h>
         ^~~~~~~~

[download]

by creating the symlink

/usr/local/include/idna.h

which points to

/usr/local/include/idn2.h

Thank you in advance for any pointers.
