You need to replace the space.  To do this you need to play a trick on
make since make treats whitespace as a word delimiter.  However, it's
easy to do once you know the secret: hide the special character inside a
variable: make only expands things AFTER it's parsed the function.
Here's how I do it:

  E := #empty variable
  S := $(E) $(E)#one space

        ... $(subst $(S),;,$(dir $(wildcard */*.h)))
