Actually, I think I see the problem:

    QT_QMAKE_EXECUTABLE:PATH=C:/Qt/Qt5.6.2/5.6/msvc2015_64/bin/qmake.exe
    QT_DIR= C:/Qt/Qt5.6.2/5.6/msvc2015_64/bin

Both of these are wrong. QT_QMAKE_EXECUTABLE is for Qt4 and QT_DIR is
unused. You'll want to set:

    Qt5_DIR=C:/Qt/Qt5.6.2/5.6/msvc2015_64/lib/cmake/Qt5
