Build failure: libutp (transmission)

Start with libutp's CMakeLists.txt at line 1 and reproduce the transmission dependency build using the Hydra job or the reported Nix build command. Confirm that configuration succeeds with the current CMake version and that transmission no longer fails because of libutp.

Nixpkgs version

• Unstable (25.11)

Steps to reproduce

• build transmission

Can Hydra reproduce this build failure?

The last build job was manually cancelled.
