# This function is used to add a project to the build in the case where the current directory only contains 
# 'branches', 'tags' and 'trunk' directories of a single project. The project will be added using the 
# branch specified (if any) in the root CMakeList.txt or trunk otherwise.
#
# The branch variable name that is checked is made up from ${CURRENT_BRANCH_PREFIX}_${DIRNAMEUPPER}. 
#
# The script also adds the directory to the global list of projects.
