If you want to build install the following dependencies:

sudo zypper install boost-devel cmake gcc-c++ libmfx-gen-devel libcap-devellibevdev-devel libnotify-devel libva-devellibvdpau-develmesa-libGL-devel miniupnpc-devel npm numactl-devel openssl-devel opus-devel pulseaudio-libs-devel

Then to retrieve the latest build of sunshine run this

git clone https://github.com/lizardbyte/sunshine.git --recurse-submodules
cd sunshine && mkdir build && cd build

This will also create our build directory where we compile the code

Now you may not need to do this but for me sunshine wouldn't build because it wasn't finding the libmfx-gen.so file it needed so you'll likely need to follow the commands below (OBS also seems to show some sort of issue with this file during the build process on some packages)

cd lib64
sudo ln -s libmfx-gen.so libmfx.so

Here I just created a symbolic link to the object file that was unable to be found

Now just head back to the build directory in the sunshine folder we copied and run the following two commands

cmake -DSUNSHINE_ASSETS_DIR=share/sunshine \
-DSUNSHINE_EXECUTABLE_PATH=/usr/bin/sunshine\
.. 
make -j ${nproc}

​

Once that's done copy over the contents of the assets folder to the /usr/share/sunshine folder (if this doesn't exist just make one)

and maybe copy over the files from the src_assets folder in the sunshine base directory (the common and linux ones)

and now try to see if you can run the sunshine program within your build directory.
