As stated above, the tdelibs framework replaces and updates kdelibs for KDE 3 and as a natural consequence inherits a build script which, with some updates, will be able to build a working binary package for Slackware 14.0. '''Tdelibs was ported to [http://www.cmake.org cmake]''' as many other prerequisite packages; as a consequence the SlackBuild script is in need of heavy rewriting. The project guidelines were strictly followed: '''/opt/trinity''' was configured as the root directory for the package ensuring TDE coexistence with KDE 4. The last suggestion comes from the [http://www.trinitydesktop.org/wiki/bin/view/Developers/HowToBuild TDE building how-to]. It consists of enabling the '''-DCMAKE_SKIP_RPATH="OFF"''' cmake option at configuration time to enable the package to execute binary files during the build process. For further information regarding '''cmake''' and its '''RPATH''' related options please consult the [http://www.cmake.org/Wiki/CMake_RPATH_handling program documentation]. Some script lines of code and related comments follow.

Once the configuration successfully concludes, the script runs the make command then goes on with packaging the software.
