libdmtx preset project

[ecolner]

Working on libdmtx integration using the presets wiki, but unfortunately have gotten stuck. I'm not well versed in the Javacpp Presets build tool, nor C syntax so looking for feedback on possible causes of errors. Building on Windows 10 64-bit right now. There is working DLLs and JNI code that I built standalone using the dmtx-wrappers Java project and Visual Studio 2022. So if interested in seeing this work off-the-shelf I'll gladly attach the artifacts.

Forked the Javacpp Presets repo and added libdmtx to it here:
https://github.com/ecolner/javacpp-presets/tree/master/libdmtx

Build log:
libdmtx-build.log

The starting point for this task is this page: https://github.com/bytedeco/javacpp-presets/wiki/Create-New-Presets

It looks like libdmtx has project files for CMake, so that's what we should be using in this case to build on Windows with Visual Studio. It's usually easiest to use in combination with Ninja and MSYS2. You can see a simple example of that in this cppbuild.sh file:
https://github.com/bytedeco/javacpp-presets/blob/master/lz4/cppbuild.sh
That file may work pretty much as is for libdmtx, but let me know if you have any questions about that!

Unfortunately, the makefile is a red herring. I found it's not useful for this project, at least on Windows.
I followed the wiki to set up the project and attempt build. The build log shows how far along the project got before failing javacpp-compiler phase.

What do you think about using the msbuild command to build the libdmtx.dll with the .sln like this?

The makefile is probably for Unix. On Windows, the easiest option is probably CMake.

But you can try with MSBuild, sure.
