this is the only line that cares about the difference:

        b.graceful = arg_graceful() == ARG_GRACEFUL_FORCE ||
                (operation == INSTALL_UPDATE && arg_graceful() != ARG_GRACEFUL_NO);

I am running into strange issue with cmakeFlags not propagating to cmake configurePhase

but this is missing all of the flags defined in cmakeFlags:

https://github.com/NixOS/nixpkgs/pull/537105/changes#diff-f169fc685573d8eaee885af02b69ba1a718da48f3a9ae1ee4bb64ca67cadef28R62-R82

I looked back at a hydra build for same package, but those flags are there: https://hydra.nixos.org/build/328605767/nixlog/1

only diff i can see is:

-- The CXX compiler identification is Clang 21.1.8
-- The C compiler identification is Clang 21.1.8

vs

-- The CXX compiler identification is GNU 15.2.0
-- The C compiler identification is GNU 15.2.0
