Compiling Qt without tslib and using USB mouse and keyboard

For the application I am programming on the 6410, I dont need touchscreen
support. Therefore a USB mouse and keyboard will be used. Because of this,
I didnt configure Qt with the option of "qt-mouse-tslib". Is that OK?

Also, I know that there are configurations needed for tslib. How do I
change the configurations below in /etc/profile so as to enable the USB
mouse and keyboard?

export LD_LIBRARY_PATH=/usr/local/tslib/lib
export QTDIR=/usr/local/Qt                 
export QWS_MOUSE_PROTO=tslib:/dev/input/event0
export TSLIB_CALIBFILE=/etc/pointercal        
export TSLIB_CONFFILE=/usr/local/etc/ts.conf  
export TSLIB_CONSOLEDEVICE=none               
export TSLIB_FBDEVICE=/dev/fb0              
export TSLIB_PLUGINDIR=/usr/local/tslib/lib/ts
export TSLIB_TSDEVICE=/usr/local/tslib/lib/ts 
export TSLIB_TSEVENTTYPE=INPUT                
export QWS_DISPLAY=LinuxFB:mmWidth=105:mmHeight=140
