I have a third party SDK for C++ with some .dll .h .lib files. I follow this tutorial. I placed them at [project]/ThirdParty/Usens/bin , [project]/ThirdParty/Usens/include and [project]/ThirdParty/Usens/lib .
and the Build.cs is here
However, when I include one of the .h file in one of my unreal project’s .cpp file and compile, the unreal editor’s compile button will disappear.
