On Linux, the following dependency is missing: libgstapp-0.10.so.0
Error log:
~/.local/share/Steam/steamapps/common/Spriter$ ./Spriter\ Pro
./Spriter Pro: error while loading shared libraries: libgstapp-0.10.so.0: cannot open shared object file: No such file or directory
We can install the dependency with apt-get: sudo apt-get install libgstreamer-plugins-base0.10-0
Note that the permissions of the libraries are wrong, everything is "executable" while only Spriter Pro should be.
