ConnectionFX3 = LimeSDR USB support.
ConnectionFTDI = LimeSDR Mini support.
So Lime Suite would support the SDR hardware directly.
SoapySDRLMS7 = support for using the SDR via SoapySDR.
Hence it’s not finding your SoapySDR installation. If you installed this via packages, you would need to have libsoapysdr-dev installed for Lime Suite to build the SoapySDRLMS7 module for it. If you built SoapySDR from source and it’s installed to /usr/local/, then it should find it.
