安装qt-arm开发环境出现下面的信息：
Creating qmake. Please wait...
gmake: Nothing to be done for `first'.
The tslib functionality test failed!
You might need to modify the include and library search paths by editing
QMAKE_INCDIR and QMAKE_LIBDIR in
/home/liu/qtarm/qt-everywhere-opensource-src-4.6.3/mkspecs/qws/linux-arm-g++.
我已经在qmake.conf 文件添加了QMAKE_INCDIR=/tslib/include/
QMAKE_LIBDIR=/tslib/lib/
