On platforms like Linux, shared libraries should have a SOVERSION which states the API version of that library. This is important if you want distros to pick up any of your libraries.

To do this, simply add a line like this in libshaderc/CMakeLists.txt:

set_target_properties(shaderc_shared PROPERTIES SOVERSION 1)

where 1 is the API version.
