Build error in uhd_signal_source.cc.o

[arch-dawson]

When building, I am encountering this error. I am running arch linux and followed the instructions in the readme.

This looks like a UHD issue, not an GNSS-SDR issue. Our code is just including theirs.

Same error, dont know why. I have built and installed the uhd but the error still. Ubuntu 22.04

Well i have found a solution to the error from #725 , just append -DENABLE_UHD=OFF after cmake .. (which is cmake .. -DENABLE_UHD=OFF) and build without error.
I dont have a uhd device so without usrp support just fine for me.

To clarify, as of C++20, the UHD code is invalid. See https://stackoverflow.com/a/65898493/9220132.

I would look for a newer UHD implementation, or downgrade to C++17.
