Add desktop, icon and appdata files for Linux installs
Follow-up on #13 (closed).
We should install a desktop file in ${CMAKE_INSTALL_PREFIX}/share/applications/lugaru.desktop
and an appdata file in ${CMAKE_INSTALL_PREFIX}/share/appdata/lugaru.appdata.xml
.
For the desktop file, we'd also need an official icon to put either in ${CMAKE_INSTALL_PREFIX}/share/icons/lugaru.png
or (better) ${CMAKE_INSTALL_PREFIX}/share/icons/hicolor/*/apps/lugaru.png
.
I can handle the desktop file, icon and installation instructions in CMakeLists.txt. @Conan_Kudo If you're up to contribute an appdata file, would be great :)
