Guarantees that a component's project_include.cmake will be called after its dependent components'
project_include.cmake. Because of cycles in the dependency graph, this is less useful than you'd
think but it gives a strong guarantee for any component which is not part of a cycle.
Also applies deterministic ordering (ordering is initialised as COMPONENT_REQUIRES_COMMON then all
COMPONENTS in alphabetical order, but then the sorting by dependencies is applied.)
