Libstellarsolver-dev dependency

[Eric Dejouhanet]

> You have the complete log? The latest libstellarsolver installs libstellarsolver.so.1.5

The log I pasted is the failure of the KStars cmake configuration. It
is still current as of today.
The latest libstellarsolver may install that library, but it is indeed
not put at the right location, and cannot be found.
This is for arch amd64.
