Need help to cross compile x86/64 to mips_24kc

Hi, I'm trying to cross compile this https://github.com/rtlsdrblog/rtl-sdr-blog over to work in my WNDR3700v1. https://openwrt.org/toh/hwdata/netgear/netgear_wndr3700_v1
I've followed the steps here... https://openwrt.org/docs/guide-developer/crosscompile but it just doesn't work. :frowning:
The files need cmake to build, so I'm not sure how to bypass that and just like make do the job.
If anyone knows how to cross compile packages, that would be great if you could help me out.

The easiest solution is to create a package...

Here are some examples and links (at least one example is with cmake):

Hi, I tried to do that but had no luck. I also tried editing the makefile for the rtl-sdr package to point to the rtl-sdr blog driver package but it got the defaults instead. :frowning:
