 ## Build, Configuration and Testing Infrastructure
+- Added the CMake exported ROOT libraries into the ROOT:: namespace. In this way, projects based on CMake using ROOT can avoid
+  conflicts in library target names. As an example, this is the way to build a project consisting of one library and one 
+  executable using ROOT.
+
+```
+find_package(ROOT REQUIRED)
+include(${ROOT_USE_FILE})
+
+include_directories(${CMAKE_SOURCE_DIR} ${ROOT_INCLUDE_DIRS})
+add_definitions(${ROOT_CXX_FLAGS})
+
+ROOT_GENERATE_DICTIONARY(G__Event Event.h LINKDEF EventLinkDef.h)
+
+add_library(Event SHARED Event.cxx G__Event.cxx)
+target_link_libraries(Event ROOT::Hist ROOT::Tree)
+
+add_executable(Main MainEvent.cxx)
+target_link_libraries(Main Event)
