Because I used to compile the GRASS with Visual C++ - before I fixed
some malloc()/free() problems that cause the original mingw build libs
to crash, when called from VC code.

The grass-vc package containing the "misnamed" libraries is not needed
anymore.  There's only the package grass-devel-vc left, that has the lib
files for VC.  But those reference the mingw built DLLs.  In your case
also unnecessary as you roll your own GRASS build.

That folder is meant to carry all external dependencies that need to be
installed with QGIS (like Qt, GDAL, PROJ, GRASS and so on).  If you have
everything in place there, you can build an NSIS installer using the
PACKAGE target out of the box (although the vcredist package still needs
to be installed).   If you don't you can just create an empty folder or
remove the reference to vcdeps from the CMakeLists.txt.
