[gnuastro-commits] master ef9e191 3/3: pkg-config file created for the libraries

[Mohammad Akhlaghi]

branch: master
commit ef9e191538bcfd9a8429d028da4f1880cd7a72c0
Author: Mohammad Akhlaghi <address@hidden>
Commit: Mohammad Akhlaghi <address@hidden>

    pkg-config file created for the libraries
    
    Following GSL's `Makefile.am', `lib/Makefile.am' now also creates a
    pkg-config file (based on `lib/gnuastro.pc.in') and installs it.
    
    The library version is now also set in `configure.ac' and used in
    `lib/Makefile.am', it isn't directly hand-written in the latter. This was
    also inspired from GSL's approach.
