Libstellarsolver-dev dependency

[Robert Lancaster]

I have myself seen some issues on some linux distributions with installing INDI drivers.  When I was making my AstroPi3 installation scripts, most of them worked fine, but there were a few that installed libraries to a lib directory where the INDI driver that depended on that library could not find it during building.  I eventually solved the issue by copying the libraries in the script to the other lib directory, but that is not the best solution.  The INDI drivers should be able to search the correct lib directory to find the libraries that were installed and the libraries should likewise install to the correct directory so that things that depend on them can find them.

Is this a similar issue?

> Hi Eric,  I am by no means an expert in this.  Originally I had the library install to the machine's libdir and to /usr/lib because on some systems it wasn’t getting found properly by other programs.  I was using the FindStellarSolver.cmake in kstars which was based on the other ones that were already there.  It used pkgconfig or an alternate method to find the library if that didn’t work.  I used the others as examples since I didn’t know the details on how to do it.  This seemed to work pretty well.  Jasem said that we just needed to install to the libdir and not /usr/lib, so we removed one of the installs.  He then said that there was some kind of craft issue with finding StellarSolver on some windows machines, although I had tested it on Windows and it seemed to work great.  He said that Hannah said that we should be doing it a different “modern” way and not use the FindStellarSolver method that we were using, so he set it up her way, both in KStars and StellarSolver.  Possibly somewhere in those changes it stopped working for some machines.  As far as Jasem and I can tell on our machines it works fine.  If you know what the problem is and know how to fix it, please enlighten us.
