1) Eliminate all teams not tied for the lead
2) Play another round with the remaining teams
3) Check for the winner again at the end of that round. If there's another tie, repeat the procedure
# - Try to find the Clang/LLVM executable
# Once done this will define
#
# CLANG_FOUND - system has Clang
# CLANG_VERSION - Clang version
# CLANG_EXECUTABLE - Clang executable
