[CMake] Tracking include_directories behavior ?

[Julien Malik]

Hello,

Is there a way to track the state of the include directories list during 
configuration ?

I'm facing a bug in include order in a pretty big project, with 
dependencies on other projects with cmake "use" file (like ITK), some of 
them using BEFORE in include_directories, others not. It gets pretty 
messy in the end.

It does not behave as expected, and I would like to print the current 
status of include directories list at several places (before importing 
project A, after, at some places in my own CMakeLists files etc...) to 
track down a bug I don't understand yet.

Thanks in advance,
Julien
