Looking at the instructions on the website to build from source there is a missing dependency for blueprint-compiler
Using the packages for Fedora listed at https://ghostty.org/docs/install/build#fedora
`blueprint-compiler` not found.
Ghostty requires version 0.16.0 or newer of
`blueprint-compiler` as a build-time dependency starting
from version 1.2. Please install it, ensure that it is
available on your PATH, and then retry building Ghostty.
Compile works once the extra package is installed.
