DiRT Rally wont start anymore due to OpenSSL 1.1

This is a fresh install of Leap 15. This happens in the console when running DiRT Rally from Steam:


/mnt/data/Spiele/steamapps/common/DiRT Rally/bin/DirtRally: /usr/lib64/libldap_r-2.4.so.2: no version information available (required by /mnt/data/Spiele/steamapps/common/DiRT Rally/bin/../lib/x86_64/libcurl.so.4)
/mnt/data/Spiele/steamapps/common/DiRT Rally/bin/DirtRally: /usr/lib64/liblber-2.4.so.2: no version information available (required by /mnt/data/Spiele/steamapps/common/DiRT Rally/bin/../lib/x86_64/libcurl.so.4)
/mnt/data/Spiele/steamapps/common/DiRT Rally/bin/DirtRally: /usr/lib64/libssl.so.1.0.0: version `OPENSSL_1.0.1' not found (required by /mnt/data/Spiele/steamapps/common/DiRT Rally/bin/../lib/x86_64/libcurl.so.4)
SIGHUP(1): Program Hangup (GPU driver issue?).

I guess I would probably have to provide OpenSSL 1.0.1 by myself. Anyone has a hint for me?

Cheers,
Bernd

Note to self: This issue is fixed with starting Steam this way:


STEAM_RUNTIME_PREFER_HOST_LIBRARIES=0 steam
