If you're talking about OpenWrt, https://openwrt.org/docs/guide-developer/build-system/start

If not, you would be better off on a forum that supports the hardware itself.

You need to either use the full OpenWrt build environment or the SDK as you need to link against the proper libraries and kernel ABIs. Any effort on your own to create your own cross-compile environment would effectively need to replicate what is already available in those build chains.
