Hello,

My system config:

Host OS: Windows 10

Guest OS: VirtualBox Ubuntu 20.04.3 LTS

UHD version: 3.15.0.0

GNU Radio version: 3.9

SDR Device : RTL-SDR Dongle

I got the below error while executing the make command:

>thangz@thangz-VirtualBox:~/Desktop/gr-osmosdr/build$ cmake -DCMAKE_PREFIX_PATH=/usr ../

.

.

make[1]: *** [CMakeFiles/Makefile2:417: lib/CMakeFiles/gnuradio-osmosdr.dir/all] Error 2

make: *** [Makefile:141: all] Error 2

What may I do to fix this error? What am I missing here? Please help!

PS: I just need the RTL-SDR component, so I installed the dependency for that alone (see complete log file).
