PX4 Navio2 Raspberry Pi Enabling Mocap

I am currently using Navio 2 with RPi 3 for running PX4 firmware. Followed the guide in documentation for cross-compiler build: https://dev.px4.io/en/setup/building_px4.html

I want to use Motion capture for flying indoors and referred to some notes:

I need to set LPE_FUSION parameters however, the RPi build seems to have only EKF verison. Is there a way to compile a LPE version for RPi? @LorenzMeier

@hardik were you able to achieve external_position_estimation using motion-capture for RPi?
