Dependency "gobject-introspection-1.0" not found,

[Waldorf3]

Tryna install this on my Thinkpad X1 Gen 4 with Fedora 40 (workstation edition if that matters). I'm trying to follow the instructions given here under Fedora 28. I realize that is long ago, but seems to be the latest offered. Anyway I get this error:

libfprint/libfprint/meson.build:255: DEPRECATION: Project uses feature that was always broken, and is now deprecated since '1.3.0': str.format: Value other than strings, integers, bools, options, dictionaries and lists thereof..
Did not find CMake 'cmake'
Found CMake: NO
Run-time dependency gobject-introspection-1.0 found: NO (tried pkgconfig)

libfprint/libfprint/meson.build:318:32: ERROR: Dependency "gobject-introspection-1.0" not found, tried pkgconfig


WARNING: Running the setup command as `meson [options]` instead of `meson setup [options]` is ambiguous and deprecated.

I'm not a developer and are out of my depth here, but would dearly love to get my fingerprint doodah working...
