There is one big issue with precompiled headers -- you only have one
such header. So it is all or nothing, This is problematic, I tinkered
a lot with PCH and various configurations. So far the best:
- Use forward declarations
- Include only that you need
Gives much better performance then
- Include everything in PCH
- Include PCH everywhere.
