[CMake] Program with Qt opening with a bash screen on windows before showing the gui...

[Michael Jackson]

This is what I have in my own CMakeLists.txt file:

   # ------------------------------------------------------------------------------
   #  Qt 4 Section
   # ------------------------------------------------------------------------------
   # by default only QtCore and QtGui modules are enabled
   # other modules must be enabled like this:  
   IF (WIN32)
       SET (QT_USE_QTMAIN TRUE)
   ENDIF (WIN32)

   # this command finds Qt4 libraries and sets all required variables
   # note that it's Qt4, not QT4 or qt4
   FIND_PACKAGE( Qt4 REQUIRED )
