I have written a Julia wrapper for a [C++ library](https://github.com/PythonOT/POT/tree/master/ot/lp) using `CxxWrapper` . I don’t have much experience with C++ but I managed to compile everything with `cmake` into a shared library and I can call the function I want from within Julia.

My question is now how do I package everything so that people can just install the package? Do I dump the build recipe into `builds.jl`? How do I make sure that `cmake` finds `jlcxx/jlcxx.hpp`? The instructions for `CxxWrap` say to use `-DCMAKE_PREFIX_PATH` but that seems a bit cumbersome. Is there an automated way for `cmake` to find `jlcxx/jlcxx.hpp`?
