QT5.6.0 鼠标支持

QT5用QPA换了QWS之后，USB鼠标就不知道怎么支持，网上搜啊搜，各种尝试，终于可以了。

./MainMenu

触摸屏还没有测试是否可以，但usb鼠标可以了。

      

      从上边也可以看到使用了evdev，所以编译时还得选上。

最终的配置为

../configure
    -release
    -opensource -confirm-license
    -no-c++11 -shared
    -no-sse2 -no-sse3 -no-ssse3 -no-sse4.1 -no-sse4.2 -no-avx -no-avx2
    -no-mips_dsp -no-mips_dspr2
    -I$TSLIB/include -L$TSLIB/lib
    -no-pkg-config
    -qt-zlib -no-mtdev
    -qt-sql-sqlite
    -qt-libpng -qt-libjpeg -qt-freetype -qt-harfbuzz
    -no-openssl -no-xinput2 -no-xcb-xlib -no-glib
    -no-qml-debug
    -nomake examples -make libs
    -nomake tools -nomake tests
    -gui -widgets
    -optimized-qmake -no-nis -no-cups -no-iconv
    -tslib -no-icu -no-fontconfig -strip
    -no-pch -no-dbus
    -force-asserts
    -no-xcb -no-kms
    -linuxfb -no-egl -no-eglfs -no-directfb -no-opengl
    -mtdev -evdev
    -xplatform linux-arm-gnueabi-g++
    -libinput
    -no-gstreamer -no-system-proxies
    -prefix $(pwd)/../../qt5.6.0 -v

      其中-mtdev 用于多点触摸，-evdev 用于鼠标键盘
