Description

This continues the work of using Clang's Build Analyzer to trace down why the build is slow.

This change further drops the compile time down like a rock. It requires that your cmake build flags are consistent and aren't mixing optimization settings.

Before I started any of this build work, an Macbook Air (M4) used to take roughly 8+ minutes to build

Now it takes
