Building Xreader from source
----------------------------

1) Install prerequisites:

    apt install git dpkg-dev
    apt install gobject-introspection libdjvulibre-dev libgail-3-dev          \
                libgirepository1.0-dev libgtk-3-dev libgxps-dev               \
                libkpathsea-dev libpoppler-glib-dev libsecret-1-dev           \
                libspectre-dev libtiff-dev libwebkit2gtk-4.0-dev libxapp-dev  \
                mate-common meson xsltproc yelp-tools

2) Download the source-code to your machine:

    git clone https://github.com/linuxmint/xreader.git

3) cd into the downloaded folder

    cd xreader

4) Run meson with options you like. The following configuration installs
   all binaries, libs, and shared files into /usr/local, and enables all
   available options:

    meson debian/build \
        --prefix=/usr/local \
        --buildtype=plain \
        -D deprecated_warnings=false \
        -D djvu=true \
        -D dvi=true \
        -D t1lib=true \
        -D pixbuf=true \
        -D comics=true \
        -D introspection=true

5) Compile and install (sudo is needed for install)

    ninja -C debian/build
    ninja -C debian/build install

6) Now you can run and test (most executables are in /usr/local/bin):

    /usr/local/bin/xreader

    If you want to test the daemon, run:

    /usr/local/lib/x86_64-linux-gnu/xreaderd

    You can enable debugging with the G_MESSAGES_DEBUG environmental
    variable.

7) You can uninstall the installed files with

    ninja -C debian/build uninstall
