Tweak cmake build that SONAME matches that of the autotools build Even if upstream does not maintain an intended SO-NAME*, the cmake build should at least yield the same result. This patch does it by hand-adjusting the version. . Update: Upstream does not care about SONAMEs much, so we need to keep this patch and deviate from upstream, until the next SONAME bump, where we then can hopefully switch to upstream's again (or switch back to autotools…). Doing the switch now would mean an unnecessary library transition.
