Unable to find blueprint-compiler for use in build

[u1f98e]

I'm trying to build Gradience using its Devel manifest, but get stopped by the final meson configuration:

Program blueprint-compiler found: NO

data/ui/meson.build:1:0: ERROR: Program 'blueprint-compiler' not found or not executable

blueprint-compiler does exist in the manifest, and running flatpak-builder manually successful builds. (Program blueprint-compiler found: YES (/app/bin/blueprint-compiler)).

I can run

flatpak-builder --state-dir=.flatpak/flatpak-builder --force-clean .flatpak/repo build-aux/flatpak/com.github.GradienceTeam.Gradience.Devel.json

after unsuccessfully building with the extension and it builds using the previous cache just fine, the extension can't run the result though as it tries to build again.

Here's the build log's section for blueprint-compiler in case it's helpful: https://pastebin.com/d4yCfzqH

I just tried building the Devel manifest and it works just fine here
