[Interest] Moc file won't compile on Android

[Joshua Grauman]

Hello all,

I am working on compiling a test program for Android. It uses 
qttoolbardialog from 
Qt5.6.2-Android/5.6/Src/qttools/src/shared/qttoolbardialog. The files are 
included in the .pro file like:

SOURCES += qttoolbardialog.cpp
HEADERS += qttoolbardialog.h
FORMS += qttoolbardialog.ui
RESOURCES += qttoolbardialog.qrc

It all works fine for the desktop version(s). But when I try to compile 
the same project for Android (using Qt Creator, which works fine for other 
projects), the moc file won't compile. The compiler output is below. Does 
anyone know what is going on??

Thanks!

Josh
