Andres,
Thank you for this. We have the build working with meson (w/o readline).
I was not able to get "readline" to be recognized by meson (I've attached
the log file)....
It is "there" according to vcpkg. (other projects have a .pc file this one
is missing?)

I did take this version of readline, and linked it to my VS sources (the
hardway), and recompiled/linked,
*and IT WORKS! With Arrow Keys, etc! (although this is like Version 5 of
readline)*

I am curious why meson is not seeing these packages as installed?
I changed the readline setting in the meson config to "enabled", but since
it doesn't "find" them,
it turns it off in the end...

Strangely it says it used pkgconfig and cmake?

I am very excited to see auto-complete and readline support coming to
windows...

Thanks, Kirk
