Good evening,

i am trying to import an out of tree module (module\_A) inside another  
out  
of tree module (module\_B) in order to be able to include header files  
from  
one to another.How can that be achieved ,and what changes would that  
require to the CMakeLists files of module\_B?

Thank you in advance
