[cmake-developers] Revitalize --find-package mode?

[Nagy-Egri Máté Ferenc]

Hi!

I’m currently struggling with trying to build GNOME projects using meson, but depending on CMake-built libraries, either in the wild or inside a package manager. I have managed to uncover that the way Meson is trying to invoke CMake

https://github.com/microsoft/vcpkg/issues/6683#issuecomment-533034646

to obtain dependency information is no longer maintained in CMake, or at least discouraged for new projects. My queries on the Meson forums did not resonate well (in fact they didn’t resonate at all):

Are there any opinions in how to make ends meet? I’m trying to build GIMP on Ubuntu LTS releases, which often have outdated packages that cannot be used to build GNOME master branches as well as build them natively on Windows using Vcpkg ports. The current method Meson tries to use CMake is totally Vcpkg-unfriendly. As far as I saw --find-package mode and toolchain failes are not friends, even configuring a one-line main.cpp fails due to basic variables not being set in --find-package mode.

What specific routes do you see viable?

Best regards,
Máté
