CMake/Source/cmGeneratedFileStream.cxx
Tim Blechmann 339c2b886a cmSystemTools: Add RandomNumber method that avoid re-seeding from OS 
When profiling Qt builds on macos, about 2.2% of a `cmake` invocation
was spent reading from `/dev/urandom`.  Use a (thread)local rng to
mitigate this cost, particularly in `cmGeneratedFileStreamBase::Open`.
