three 3d points to rotation - comparison python and cpp

Hi,
this is a method for getting the rotation between three 3d points in the space.
For the first I did this in python but was to slow so I recreated this in cpp.
In the folder you will find, project files, working dll and source code.
I"m not very good in cpp , just started this journey so for sure somebody can find more elegant way to do this operation.
anyway, it can be useful in some cases.

have a good day
