Hardware

• CPU: AMD via Oracle VirtualBox
• RAM: 32GB
• GPU:
• SDR: FobosSDR

Software

• Operating System: Ubuntu 24.04.1
• SDR++: Version 1.2.1 + Build date 5-1-25 but building today gives of course 27-1-25

Bug Description
I have latest Fobos materials installed. Also the libfobos 2.3.2
I am building sdrpp from scratch as I only want to install Fobos SDR, no other hardware.
I have set -DOPT_BUILD_AIRSPY_SOURCE=OFF -DOPT_BUILD_AIRSPYHF_SOURCE=OFF -DOPT_BUILD_HACKRF_SOURCE=OFF -DOPT_BUILD_HERMES_SOURCE=OFF -DOPT_BUILD_PLUTOSDR_SOURCE=OFF -DOPT_BUILD_RTL_SDR_SOURCE=OFF -DOPT_BUILD_USRP_SOURCE=OFF

Result : FobosSDR_source is not built and can not be chosen when sdrpp is started

For second built I have set
-DOPT_BUILD_FOBOSSDR_SOURCE=ON -DOPT_BUILD_AIRSPY_SOURCE=OFF -DOPT_BUILD_AIRSPYHF_SOURCE=OFF -DOPT_BUILD_HACKRF_SOURCE=OFF -DOPT_BUILD_HERMES_SOURCE=OFF -DOPT_BUILD_PLUTOSDR_SOURCE=OFF -DOPT_BUILD_RTL_SDR_SOURCE=OFF -DOPT_BUILD_USRP_SOURCE=OFF

Result : FobosSDR_source is built and can be chosen when sdrpp is started

My conclusion : FobosSDR is not built as a standard, like shown in the table https://github.com/AlexandreRouma/SDRPlusPlus#sources

Maybe the table is temporarily incorrect ?

further details when starting sdrpp,
Start sdrpp information from terminal
