As the name LINK_FLAGS denotes, these settings are applied when a target
is linked, i.e. built from its object files and checked for references
to libraries. They don't come into play when sources are compiled to
object files, so "-I" within LINK_FLAGS is of no use.

Consider to set the COMPILE_FLAGS source property on those files which
you want to be compiled with "-I" flags for special include directories.
