Mint build from source - libosmosdr.so.0 error

[krutzy62]

I am trying tried to build SDR++ from source, since the .deb gave me issues, on Linux Mint V21 (Vanessa (Ubuntu Jammy)). W want to use it with a RTL-SDR V3.
In the CMAKE step I used the option -DOPT_BUILD_RTL_SDR_SOURCE=ON. The program starts but then terminates with the error:
[ERROR] SoapySDR::loadModule(/usr/lib/x86_64-linux-gnu/SoapySDR/modules0.8/libosmosdrSupport.so)
dlopen() failed: libosmosdr.so.0: cannot open shared object file: No such file or directory

Is there a step or perquisite I missed?

Thank you.

I would like to add that the entire error is:
[ERROR] SoapySDR::loadModule(/usr/lib/x86_64-linux-gnu/SoapySDR/modules0.8/libosmosdrSupport.so)
dlopen() failed: libosmosdr.so.0: cannot open shared object file: No such file or directory

In the /usr/lib/x86_64-linux-gnu/SoapySDR/modules8.0/ directory there is an entry for libosmosdrSupport.so however there is no entry libosmosdrSupport.so.0. In the /usr/lib/x86_64-linux-gnu/SoapySDR/ there is and entry for libSoapyOsmoSDR.so.0.8 if that means anything.
