I was jumping up and down earlier today because I managed to package ZTE and build it successfully from source: [nixdots/modules/nixos/opt/openziti/default.nix at main · rochecompaan/nixdots · GitHub](https://github.com/rochecompaan/nixdots/blob/main/modules/nixos/opt/openziti/default.nix). Additionally, I had no CA and cert troubles either! Consider this a WIP since I'm still testing if everything works end-to-end. I encountered the same issue mentioned in the hard-coded paths discussion here: [Hard coded executable paths](https://openziti.discourse.group/t/hard-coded-executable-paths/791). I fixed this by [patching](https://github.com/rochecompaan/nixdots/blob/main/modules/nixos/opt/openziti/default.nix#L90) paths to use Nix package paths. The other challenge was to pull in all the dependencies using Nix fetchers instead of vcpkg, but I compiled the list of dependencies by reviewing the various CMakeLists.txt files. I'll start a new topic about the Nix package once I'm done. --- _[View the full topic](https://openziti.discourse.group/t/how-to-login-using-external-jwt-signer-with-linux-tunneler/5160)._
