### Loupe Dependencies

#### Required

glycin-2.1.1 (runtime), Little CMS-2.19, libadwaita-1.9.0, libgweather-4.6.0, libseccomp-2.6.0, and rustc-1.95.0

#### Optional

## Installation of Loupe

Install Loupe by running the following commands:

    mkdir build &&
    cd    build &&

    meson setup --prefix=/usr       \
                --buildtype=release \
                ..                  &&
    ninja

Running the test suite will rebuild the entire package with a different configuration, and the package will be built for three times if installing it after running the test suite. So it's better to run the test suite after the installation.

Now, as the `root` user:

    ninja install

To test the results, issue: ninja test

If you've installed Eog (which is unmaintained and removed from BLFS) before and you want file managers (such as Nautilus) to open image files using Loupe instead of Eog, remove the desktop file for Eog as the `root` user:

    rm -fv /usr/share/applications/org.gnome.eog.desktop

## Command Explanations

`--buildtype=release`: Specify a buildtype suitable for stable releases of the package, as the default may produce unoptimized binaries.
