[CMake] Installing Find*.cmake to the correct folder using NSIS configured by cmake on windows platform

[Mika.Rajala at patria.fi]

Hi

How can i tell the NSIS installer, using cmake, to install my Find*.cmake
script to the ${CMAKE_ROOT}/Modules directory?

Writing that to the "install" command doesn't work.

I did try googling for anwsers for the better part of yesterday so if it
can be found on the internet, please provide some assistance.
