Creating a project for Visual Studio 2019 works:

The used standard is c++17. The master version of CxxWrap.jl is installed and compiled via Pkg.

Sorry for the late reply. The problem is that jlqml wasn't updated yet for the master version of libcxxwrap-julia. I just pushed my changes to both QML.jl and jlqml, so now it should work if you build both jlqml and libcxxwrap-julia from source.

Thanks for your quick changes. Unfortunately I now have the problem that I cannot load the created jlqml.dll in julia.

I build libcxxwrap in Visual Studio 2019 as release version for x64, added ENV["JLCXX_DIR"] = "C:\\Users\\Martin\\Projekte\\Builds\\libcxxwrap-build" in julia and pkg> build CxxWrap with the latest master of CxxWrap.jl.

Next I cmake jlqml

There is no folder Found JlCxx at C:/Users/Martin/Projekte/Builds/libcxxwrap-build/bin/Debug only Release. I copied the files from Release to a new folder Debug und also compiled jlqml as Release with x64 in Visual Studio 2019 without Errors (but some warnings) and added the path as described to julia ENV

After a few attempts, I found out that for `build QML' libjlqml.dll is expected instead of jlqml.dll and this is copied to the subfolder bin and renamed. However, the corresponding dll cannot be loaded into julia.

julia> Libdl.dlopen("C:\\Users\\Martin\\Projekte\\Builds\\jlqml-build\\Release\\jlqml.dll")

This should work now, at least with Julia 1.3 and if libcxxwwrap-julia is also compiled with MSVC. Newer versions of Julia don't work because of JuliaLang/julia#34201
