     If problems do arise, they can always opt-out by defining `CPM_USE_LOCAL_PACKAGES`, which will override all calls to `CPMAddPackage` with `find_package`.
     If you are using `CPMFindPackage` instead of `CPMAddPackage`, CPM will always try to use `find_package` to add packages.
     This approach should be compatible with any common C++ package manager without any user intervention, however at the cost of reproducible builds.
