[ELPA Syncer]

branch: elpa/pdf-tools
commit a1048bceb2bd3f635437b0f2bfac27cae8c2dabc

    Fix: Update PKG_CONFIG_PATH to add glib headers
    
    Copying my comment from the Github issue:
    
    > The problem is that something seems to have changed in the way brew
    > installs glib, due to which pkg-config does not find the glib headers.
    >
    > To fix this, I have updated the autobuild script to manually modify
    > the PKG_CONFIG_PATH. This should fix the problem.
    >
    > I will test the change and close this issue via the commit once I push
    > it. You will need to update your version of pdf-tools and then restart
    > Emacs to trigger the re-build again. (It might take a few hours for
    > Melpa to pick up the latest version of the pdf-tools)
    >
    > I will create a linked issue to investigate a better long-term
    > solution to this problem.
    
    Closes: #269
