On FreeBSD, when 3.3.0 is built with cmake, the installed libraries are only .so files, and this is not sufficient to be registered by ldconfig: these libraries cannot be used by their consumers.
The attached patch, proposed by Thomas Helfer, make it install .so.3 (major) and .so.3.3.0 (version), with symlinks, and the problem is solved.
Fixed in:
rliv-3.0
rliv-3.1
rliv-3.2
rliv-3.3
