Build docviewer with libreoffice support for xenial

[chris]

while pdf files should already work, it was not yet possible to build a docviewer packages with libreoffice support.
I wanted to post the steps I already did and the results

Here some screenshots to the steps described in https://github.com/ubports/docviewer-app/pull/25

If you uncomment the line "#INSTALL( DIRECTORY ${UPSTREAM_LIBS_DIR}/opt/libreoffice/lib/libreoffice/ DESTINATION ${DATA_DIR}lib/${ARCH_TRIPLET}/libreoffice )" in Click.cmake, you get a click package without libreoffice support (e.g. text and pdf files work).

If you try to open an odt file, you get the message:

If you add (e.g. in a chroot environment with clickable --container-mode) libreoffice to the dependencies, and put the line " #INSTALL(DIRECTORY /usr/lib/libreoffice/ DESTINATION ${DATA_DIR}lib/${ARCH_TRIPLET}/libreoffice )" to the Click.cmake, you get an about 80MB click package.

Again opening an example odt file, you now get:

In the logviewer you see, for example:

After adding the missing dependencies, at some point it was no longer complaining, the screen looked like:

and the corresponding log:
qml: Path of the document: /media/phablet/7873-B162/Documents/example.odt

LibreOffice profile path: "file:///home/phablet/.config/com.ubuntu.docviewer/libreoffice/4"
Document loaded successfully !

But at that point docviewer crashed. I will not have much time currently to look into that in more detail, but at least that is where I got on Saturday...

Yesterday I tried the same for the amd64 clickable container (adding the dependendies manually and run in desktop mode), and got:

We got a working build now which will appear in Openstore until Friday or so. Thanks for your efforts!
