Is "userprofile" an absolute path? (sorry I'm not working on Windows very often)
if this is the case this will not work.

DO NEVER install with absolute install path on Windows:
   1) the installed pieces won't be put in the installer
   2) the files/dirs/whatever MAY (if you have enough privilege) be
installed on the machine
       on which you are trying to build the package!!

I think we should forcibly forbid absolute install path on
windows...but that's another story.

Usually you go from to native path representation using

file(TO_NATIVE_PATH path result)
file(TO_CMAKE_PATH path result)

see:
cmake --help-command file

this one looks wrong:
CPACK_NSIS_INSTALLED_ICON_NAME
       A path to the executable that contains the installer icon.

> set(CPACK_PACKAGE_ICON "Company")

same for this one:
CPACK_PACKAGE_ICON
       A branding image that will be displayed inside the installer.

the documentation currently found  in CPack.cmake
or http://www.cmake.org/Wiki/CMake:CPackPackageGenerators#NSIS
(and soon from cpack --help-variable)
could be improved but both the previous variables should refer to files.

I think this one refers to a executable installed by the project.
(but there is not documentation [yet] for "CPACK_CREATE_DESKTOP_LINKS" :-]

> set(CPACK_PACKAGE_INSTALL_DIRECTORY "${PROJECT_NAME}") # add the version

> set(CPACK_PACKAGE_DESCRIPTION "Package ${PROJECT_NAME}")

there is no such variable.
There is:
CPACK_PACKAGE_DESCRIPTION_SUMMARY
       Short description of the project (only a few words).
CPACK_PACKAGE_DESCRIPTION_FILE
       A text file used to describe the project.

       Used, for example, the introduction screen of a CPack-generated
       Windows installer to describe the project.

A lot of things...
first did have a look at the error:
"H:/long_path/_CPack_Packages/win32/NSIS/Minimum Drag-0.1.1-win32\*.*"

is it true?

then open the project.nsi file and try to fix things "by hand".
then go back to your
