[CMake] Performance profiling for CMake scripts?

[Robert Maynard]

I am not aware of any built in functionality that can generate
performance numbers for a project.

Have you made sure that the performance/parsing policies are set to
NEW or your cmake_minimum_required is sufficiently high, those can
have a significant improvement on configuration time.

Polices ( both in CMake 3.1 )
 - CMP0054 'if parsing'
 - CMP0053 'simplified variable reference and escape parsing'
