Here's what I needed to run (as root) in order to get the prerequisities installed for OpenSUSE Tumbleweed:

zypper in libSDL2_net-2_0-0 libsndio7_0 libfluidsynth2
ln -s /usr/lib64/libsndio.so.7.0 /usr/lib64/libsndio.so.6.1
ln -s /usr/lib64/libcurl.so.4 /usr/lib64/libcurl-gnutls.so.4
ln -s /usr/lib64/libfluidsynth.so.2 /usr/lib64/libfluidsynth.so.1

Unfortunately, the game requires specific library versions that OpenSUSE doesn't provide, which is where the symlinks come from. From what I've read, libcurl on OpenSUSE has libcurl-gnutls built-in, which is where that symlink comes from.

The developers of ScummVM officially offer only the source code that you have to compile for your Linux and libraries. The version built into the game and compiled by GOG probably doesn't work well with openSUSE.

A somewhat easier and more optimal solution is to download ScummVM directly as a binary package from the openSUSE repository, unpack the RPM and replace the ScummVM files in the installation directory of Blade Runner with those from the RPM.

Self-tested - runs.
