I don't understand the point of installing headers or pkg-config files.

This does solve #6 though I would suggest only installing the library if default_library is shared or both.

Apologies for the delay.

Your project libraries get linked to libfmt.so from the wrap that gets built.

Makes sense. Fixed.

Sorry for the delay, just saw this in the notification area. Nowadays wraps should have a [provide] entry. With that added this should be good to merge.

Now that we're getting a meson install flag to skip installing subprojects, I'm less bothered by an addition like this. :)
