Add libx11 to openSUSE build dependencies (#35553 )
building on opensuse fails without `libx11-devel` **Repro:** ```bash $ cd $(mktemp -d) $ git clone https://github.com/zed-industries/zed . $ docker run --rm -it -v $(pwd):/zed -w /zed opensuse/tumbleweed (opensuse) $ curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh (opensuse) $ ./script/linux (opensuse) $ cargo build --release ``` **Expected:** to work **Actual:** ``` thread 'main' panicked at /root/.cargo/registry/src/index.crates.io-1949cf8c6b5b557f/x11-2.21.0/build.rs:42:14: called `Result::unwrap()` on an `Err` value: pkg-config exited with status code 1 > PKG_CONFIG_ALLOW_SYSTEM_LIBS=1 PKG_CONFIG_ALLOW_SYSTEM_CFLAGS=1 pkg-config --libs --cflags x11 'x11 >= 1.4.99.1' The system library `x11` required by crate `x11` was not found. The file `x11.pc` needs to be installed and the PKG_CONFIG_PATH environment variable must contain its parent directory. The PKG_CONFIG_PATH environment variable is not set.
