# Some CMakeLists.txt in contrib/ are not being good citizens and change cmake cache variables
# globally. This policy prevents such *cache* variable assignments from altering *normal* variables
# that we've set.
# Example: suppose our root CMakeLists.txt assigns a normal variable:
#   set(CMAKE_CXX_STANDARD 23)
# then llvm-project assigns cache variable with the same name:
#   set(CMAKE_CXX_STANDARD 17 CACHE STRING "...")
# The latter assignment doesn't affect the normal variable, so llvm-project effectively uses C++23.
# Without this policy, the behavior is nonlocal and brittle: if the cache variable doesn't exists,
# the normal variable is unset; otherwise it's left alone. So the effective value would depend e.g.
# on the order in which contrib/ libraries are traversed.
