[CMake] cpack -G NSIS

[Andrea Crotti]

Thanks for the feedback,
however I tried again with another cmake file, which should actually do 
something.
What I would like to do is to:
- get the project name and a list of packages (just directories) to install
- install them somewhere (now the destination is not set correctly).

Should this work in general?

cmake_minimum_required(VERSION 2.6)
#TODO: should take from the python environment

# setting variables from some known build generated files
# probably we can also pass options directly to CMake
file(STRINGS project_name.txt project_name)
file(STRINGS package_list.txt packages)

project(${project_name})

# include can be used to add more configurations??

# # install all the given automatically
install(
   DIRECTORY ${packages}
   DESTINATION test_ddest
   )

#TODO: how do I get the correct destination for windows?

# now the packages variable should contain something

# this include all the necessary
include(CPack)

But I still get the same error using NSIS (works with TGZ):
