commit 1ccea05b6e3bc8019af493c041318ae8bceef920
Author: Geert Janssens <geert at kobaltwit.be>
Date:   Sat Feb 8 13:54:28 2020 +0100

    CMake - drop LC_ALL=C for generation of appdata and desktop files
    
    It doesn't seem to have any noticable effect.

commit cce69e37d27d2a48e1bd4f2b9e0ed2d4ebaaeaf5
Author: Geert Janssens <geert at kobaltwit.be>
Date:   Sat Feb 8 11:44:40 2020 +0100

    Rework appdata and desktop file generation
    
    - attempt to merge in translations before merging in version data
    - add the intermediate file (with translations) to the dist tarball
    - dist builds no longer have to run the translation merge, but can instead
      use the included intermediate file. This accomodates distros with
      older gettext versions.

commit 8243496ed0b3ea50d399422f0cc7ced713d2ea64
Author: Geert Janssens <geert at kobaltwit.be>
Date:   Fri Feb 7 21:56:21 2020 +0100

    Rework our gettext tests
    
    - only abort configuration if gettext is older than 0.18.1 (required for string extraction from scheme files)
    - otherwise always continue but disable a few other build steps depending on the gettext version
    - use feature variables to more clearly convey what is enabled or disabled
