 ### Compiling source code
 
 Runtime dependencies are Qt X11 Extras, gtk-update-icon-cache, hicolor-icon-theme and Openbox.   
-Additional build dependencies are CMake and [liblxqt](https://github.com/lxde/liblxqt), optionally Git to pull latest VCS checkouts. The localization files were outsourced to repository [lxqt-l10n](https://github.com/lxde/lxqt-l10n) so the corresponding dependencies are needed, too. Please refer to this repository's `README.md` for further information.

 Code configuration is handled by CMake. CMake variable `CMAKE_INSTALL_PREFIX` has to be set to `/usr` on most operating systems.
