I don't see compiler/linker invocations for any of the plugins in the gitlab
output, so it seems to be a build system issue. When running locally in a
Docker container, Qbs builds correctly. I have put above lines (without
invoking python build.py) in a Dockerfile and ran
Then I started a container with
docker run -it --rm -v $PWD:/builds -w /builds qbsconan
and invoked the build with
docker exec CONTAINER_ID python build.py
I guess this is a bit closer to what gitlab is doing, but maybe not 100%. So
what could be the difference?

Yes, a Qbs Conan package in the bincrafters repo or in
https://conan.io/center/ would be great. I thought about just packaging
prebuilt binaries containing bundled Qt libraries as a first step for the
1.16 release. The next Qbs release could then be built from source using the
Qbs Conan package.
But if you manage to build Qbs from source in a Conan recipe using
bincrafters' Qt package, even better. Would you contribute and maintain a
Qbs Conan package?

In an open source project where almost all participants invest their spare
time to create something useful, it is good practice to not let others
guess. Would you mind sharing your findings? You may file a bug report or
submit a fix right away.
