You are right! This is called 3 times. (Proved: by doing a print() inside
Windows.characterSetDefines())
I guess: one call for initialising qbs itself, another for the
Depends{ name: 'cpp' } in the Application { ... } block and the 3rd call
for the Depends { name: 'cpp' } in the module 'myModule'.

It does not help to clean and re-run again unfortunately. This looks like
a bug to me.
