18.04 is out of security support, and cmake for 18.04 is no longer
available via kitware's debian repository (or at least fetching it
failed for one build).
I'm not sure why this is needed now and wasn't needed before since the
cmake changes have been in main for a while and there don't appear to
be recent changes to the appimage build tools.
This change adds to lib directory to LD_LIBRARY_PATH so the appimage
tools' ldd check will pass. This is an appropriate change since the
directory that is added will be in the standard load path when
installed.
Also remove linearization from qpdf-manual.pdf. It's a small file, and
removing the dependency on the qpdf executable significantly shortens
build times.
Since the files autogen.sh creates are now controlled, you only have
to run autogen.sh when you modify the source files, not when you
build from a clean checkout.
Enhance 'build-appimage' script:
- add initial comment block and comments for all major steps in the
script for the benefit of casual users of the script
- 'configure' to build HTML + PDF documentation
- do not remove the man pages from the AppDir (will be used by custom
AppRun script)
- use a bigger icon
- use '-g' for appimagetool so it can figure out the 'updateinfo' string
on Travis CI
- output big fat warning to users who build AppImage in non-"Trusty"
environments
Add 'AppStream' metadata file
This serves to satisfy desktop environments who want to automatically
create menu entries, show screenshots and display software descriptions.
Note, this file (qpdf.appdata.xml) may need more tweaking since the
Freedesktop folks aren't exactly sure themselves how their 'standard'
should exactly look like, and they changed their validation tools
quite a bit over the recent years in incompatible ways...
Extended and enhanced customized AppRun script
- Add a '--ai-usage' invokation param to the AppImage which serves as
a starting point to explore the other embedded options
- Support displaying of manual pages by running AppImage with added
parameter '--man ...'
- Also include HTML/PDF documentation, READMEs and licenses into AppImage
- Support for more parameters: '--list-man', '--list-pdf', '--list-readme',
'--list-license', '--list-html', '--list-exe', '--pdf', '--readme',
'--license', '--html' and '--show-apprun'
- Support 'fix-pdf' and 'zlib-' as sub-commands (not just as symlinks)
