If you want to support <6.20, add this line:
include("${ROOT_DIR}/modules/RootNewMacros.cmake")
However, it was moved and included by default in 6.201

Alternative to add the dictionary to an existing target:
add_library(DictExample SHARED DictExample.cxx DictExample.h)
target_include_directories(DictExample PUBLIC "${CMAKE_CURRENT_SOURCE_DIR}")
