undefined references to stack trace functions in KMP.cpp

[edbefee3-3888-462a-9411-741b7e9eb54e]

when I try to compile RiiStudio: I get the following error:

Is -lstdc++exp present? That worked for us with Junior's Toolbox.

That failing you could configure with cmake .. -DCMAKE_BUILD_TYPE=Release -DCMAKE_CXX_FLAGS="-DRSL_STACKTRACE_UNSUPPORTED=1", though that would be a reduction of functionality and far less preferable to what Joshua suggested.

How would I add that?

We have this:

if(CMAKE_CXX_COMPILER_VERSION VERSION_GREATER_EQUAL 14)
  target_link_libraries(JuniorsToolbox PRIVATE stdc++exp)
else()
  target_link_libraries(JuniorsToolbox PRIVATE stdc++_libbacktrace)
endif()
