The update of libwebsockets from 4.4.1 to 4.4.5[^1] introduced a regression where plugins could no longer be found.[^2] This could be traced back to a change in how the installation directory is computed since libwebsockets 4.4.2[^3] and we patch it here with the correct path. Fixes https://github.com/NixOS/nixpkgs/issues/532638 [^1]: https://github.com/NixOS/nixpkgs/pull/529620 [^2]: https://github.com/NixOS/nixpkgs/issues/532638 [^3]: https://github.com/warmcat/libwebsockets/commit/bdbebaa3b5f89bd31128fceb72a4133c0a2f738d
