CxxWrap looks for older version of library

[JTreehorn]

Hi, I'm almost certain I'm missing something while building libcxxwrap-julia & installing cxxwrap, I'm quite new to julia generally. After
cmake --build . --config Release

I then create the Override file w/ correct path. Then in julia after ] add CxxWrap

julia> using CxxWrap
[ Info: Precompiling CxxWrap [1f15a43c-97ca-5a2a-ae31-89f07a497df4]
ERROR: LoadError: InitError: could not load library "/mypath/libcxxwrap-julia-build/lib/libcxxwrap_julia.0.8.2.dylib"

whereas the file I have at this location is libcxxwrap_julia.0.8.3.dylib

What essential step(s) have I skipped to make these things work together?

Thanks very much
