Integrate LEF/DEF 5.8 into the tree (Apache 2.0 licensing) * New: As, starting from version 5.8, LEF/DEF parser/drivers are availables under Apache 2.0 license, integrate them inside the project. Rewrite the Makefiles into CMakeLists.txt, build only the C++ version. Create an entry for the LEF/DEF doc in the documentation.
