     Please follow https://github.com/intel/ipu6-camera-bins README to install.
 
 - Dependencies: libexpat-dev automake libtool libgstreamer1.0-dev libgstreamer-plugins-base1.0-dev libdrm-dev
-
-- Build and install:
-    Recommend to build together with icamerasrc and using `build.sh` in this repo.
-1. Put ipu6-camera-hal, icameasrc and build.sh parallel as below:
-    ```
-    cp build.sh .. && cd ..
-    # work
-    # ├── build.sh
-    # ├── icamerasrc
-    # ├── ipu6-camera-hal
-    # └── out
-    ```
-
-2. For example, in `work` folder, run `./build.sh -d --board ipu_mtl`. Output binaries will be in `out/ipu_mtl/install`.
-   Notice: Use `./build.sh --board ipu_mtl` to disable dma build.
-           The dma build depends on 'gstreamer >= 1.23' and 'libva-drm'.
-
-3. Install built out drivers in `out/<target>/install` to target:
-    ```sh
-    cp -r ./out/<target>/install/etc* /etc/
-    cp -r ./out/<target>/install/usr/include/* /usr/include/
-    cp -r ./out/<target>/install/usr/lib/* /usr/lib/
-    ```
-
-For more building details please reference the `build.sh`.
+```sh
+# Please follow common cmake, make & make install flow
+cd ipu6-camera-hal
