How to compile the yocto rootfs after modifiying a qt app

I am using an imx6slev board and my qt version is qt 5.9 and trying to implement screen rotation for qt apps.

I read in a qt forum that qt5 doesn't support rotation and hence I had to modify the already existing qt app

(QT5 LinuxFB rotation for LCDs patch · borkedLabs )

I compiled the entire rootfs using

   bitbake fsl-image-qt5-validation-imx


but no change appears in rootfs

NOTE: Tasks Summary: Attempted 5751 tasks of which 5751 didn't need to be rerun and all succeeded.

as seen in above log rootfs was not modified

Should I change the .bb file for compiling qt base?


I have attached the .cpp and .h file and the .bb file used.


Path where I added the files:
