I’ve been having problems with my waveshare Jetson nano 4gb emmc module. im new to ubuntu.
With its limited storage, i couldnt even install jetpack sdk components. ive tried moving the root file system with to an external sd card. but it then prevented me to install the cuda accelerated opencv with the cmake error

question, is there a way to move the download path of the sdk components without entirely moving the rootfilesystem to an external sd card, which lets me build opencv with cuda. or is there a way to just fix the cmake problem on its own?
