CxxWrap required version fails to compile on Julia 1.9

[cibinjoseph]

CxxWrap.jl version 0.11.2 required for FLOWUnsteady does not compile on Julia 1.9 with the error:

ERROR: LoadError: libcxxwrap_julia_jll not available on this platform
Stacktrace:
 [1] error(s::String)

This is because libcxxwrap_julia_jll is not available in Julia 1.9. The only workaround is to use Julia 1.8. Refererence discussion thread
