Description
Describe the project you are working on
Currently making a GDExtension library for dammaku.
Describe the problem or limitation you are having in your project
Currently the only supported way to use godot-cpp is to use as a subproject of your project.
It kinda works but it's rather cumbersome because you need to rebuild godot-cpp when you build your project from scratch. This can be especially painful in CI.
Describe the feature / enhancement and how it helps to overcome the problem or limitation
What this does is add an install command to the CMake script of godot-cpp.
A GDExtension project can then use find_package
to use the built godot-cpp.
This makes it possible to share the compiled godot-cpp library among different project.
This also enables the usage with package-managers.
I have made a PR that would make godot-cpp installable.
There are other PRs that also try to address this:
godotengine/godot-cpp#1309
godotengine/godot-cpp#1041
One of the authors would like to be able to build & install this in a docker image to save time. So this would have that benefit too.
Describe how your proposal will work, with code, pseudo-code, mock-ups, and/or diagrams
find_package("godot-cpp" 4.2.0 CONFIG REQUIRED)
target_link_library("my-gdextension-project" PRIVATE "godot::cpp")
If this enhancement will not be used often, can it be worked around with a few lines of script?
The work around is using godot-cpp as a subproject, but that can undesirable (unnecessary rebuilds).
Making the library installable, would mean it's a lot easier to port this to package managers.
Is there a reason why this should be core and not an add-on in the asset library?
This feature is for godot-cpp.
