Upon rebuilding Stellarsolver, Kstars compile error locating that library.

Make Error at /usr/local/lib/cmake/StellarSolver/StellarSolverConfig.cmake:79 (message):
  The imported target "StellarSolver::stellarsolver" references the file


  but this file does not exist.  Possible reasons include:

  * The file was deleted, renamed, or moved to another location.

  * An install or uninstall procedure did not complete successfully.

  * The installation package was faulty and contained

And as matter of fact a file new version of the file appeared in /usr/lib/aarch64-linux-gnu
Note it is now 2.4, not 2.2
