What about forward declaration of the var type, and use a pointer to it.
Something like:

Qt Code:
  1. struct SomeOtherStruct;
  2.  
  3. class MyClass
  4. {
  5. ...
  6. SomeOtherStruct* other;
  7. ...
  8. }

This way you don't have to include the header here, but only in the source file.

If you don't find this acceptable, then we can see some relevant code?

Regards.
