Unable to build using buildroot

[y-runwal]

I am trying to build this utility with buildroot for SAM9X75. It's giving me following error.

`

Hi there,
It seems like you're attempting to build the upstream libcamera-apps package (v1.2.1), which is quite old and barely supported. This specific libcamera-mchp (built on top of libcamera v0.3.1) is specifically designed for Microchip's processor families, particularly those using the microchip-sama7g5-xisc ISC. Can you try using libcamera-mchp, https://github.com/linux4microchip/buildroot-external-microchip/tree/master/package/libcamera-mchp with these configs: BR2_PACKAGE_LIBCAMERA_MCHP, BR2_PACKAGE_MCHPCAM_APPS for your target? FYI, these are enabled by default for sam9x75-curiosity and sama7g5ek platforms.

Thanks.
