[CMake] CMAKE_INCLUDE_CURRENT_DIR on a function

[Craig Scott]

function() introduces a new scope, so if you want changes you make to
variables inside the function to be visible outside the function, you need
to use set(... PARENT_SCOPE). Alternatively, a macro() does not introduce a
new scope, so replacing your function() with a macro() may also yield the
behaviour you want (but changing to a macro has other effects, so make sure
you read the docs before going down that path). Also note that setting it
in one directory does not make it apply to subdirectories as well, in case
that matters in your situation.
