Thanks. I misunderstood what they do.

So a change Apple has made since MacOS 10.9 when it did build without the need of telling it to look in /usr/local/include

And with those 2.8.0 works.

On Linux it's '-rpath <directory>' that needs to be passed to the linker, and gcc doesn't have a native forwarding option, so the -Wl passthrough option is needed:

Not needed. Built fine and tested.

Which now takes me to Maildrop 3.0.0 which adds the need for libidn. Even though libidn is in /usr/local/lib and I’m configuring with:
./configure --enable-utf CPPFLAGS='-I/usr/local/include' LDFLAGS='-L/usr/local/lib’
I get
checking for LIBIDN... no
configure: error: libidn not found

I don’t see anything useful in config.log - just:
configure:12674: checking for LIBIDN
configure:12733: result: no
configure:12745: error: libidn not found
