I have created two solutions with visual studio. I compile the first as a static lib. I want to use that lib in the second solution which is a plugin for maya.
For the second solution I started from the hello world template file Autodesk provides and didn't change much or anything at all except adding the path to my lib and including it. I kept getting this errors:

After a lot of researches and tests I found out that if I would change project properties > general > project defaults > configuration from dynamic link libraries to static it would compile, although at that point when i try to load the compiled .mll file in maya I get this error:
// Error: file: C:/Program Files/Autodesk/Maya2018/scripts/others/pluginWin.mel line 290: Unable to dynamically load : C:/Users/daniele/Documents/maya/plug-ins/ddRbf.mll
// Error: file: C:/Program Files/Autodesk/Maya2018/scripts/others/pluginWin.mel line 290: (ddRbf) //
So I guess the solution is to compile the first .sln file as a dynamic link library instead, but I was wondering if there was a way to just use the static library without having to do that step.
I found the problem, I compiled the library as x86 and the plugin as x64. I compiled both as x64 now and works.
