I was suggesting that maybe you can use Guix to create this image. :-)

Obviously, it needs some love (dameon) to fit your use case. And I do
not know if it make sense but I would try to replace this Dockerfile
[1] by a manifest and "guix pack". Or maybe as a first step using
Dockerfile based on Guix instead of Alpine.


And even, instead of the raw instruction, I would use the installation
script [2].

The "guix pack" should fit your need. But I am not sure because it is
a simple cmake-build-system with few (guix) dependencies, i.e., it
"relies a lot in CMake features like ExternalProject".

All the best,
