Summary:                    AUTOUIC not generating all needed ui_xxx.h files
Description: 
The AUTOUIC feature in CMake 3 does not generate all headers included in sources
even if corresponding xxx.ui files exist.

1) In particular, if one file has more than one #include "ui_*.h", only the last
one is generated. This may be quite uncommon but happens several times in our
projects.


2) Also, even if there is only one #include "ui_*.h" per file, in some
situations only one of the corresponding headers is generated.



I set severity to Major because this makes this feature unusable in several of
our projects and we have to go back to using QT4/5_WRAP_UI...

Steps to Reproduce: 
Case 1)

forms.h:

#include "ui_form1.h"
#include "ui_form2.h" -> only this one generated

Case 2)

a.h:

#include "ui_a.h"

b.h

#include "ui_b.h"


Only one of them is generated (e.g. ui_b.h). If I comment out the #include
ui_b.h line then the other, ui_a.h is generated.



Additional Information: 
BTW, I looked at the code in cmQtAutoGenerators.cxx. Function ParseForUic (line
1779+) seems to be doing case 1. Even if the regex is tested several times in a
while loop, its matched result "basename" is always stored in the same map key,
erasing previous values:

includedUis[absPath] = basename;

basename changes in each iteration, but absPath remains the name of the header
analyzed. So there can be only one ui per header.

I do not understand why case 2 happens...
