[CMake] NSIS template variable substitution.

[Anders Lindgren]

Hi!

You can do something like:

---------------------------
set(my_list alpha beta gamma)

message(STATUS "my_list: ${my_list}")

# This converts a list into a newline-separated string.
set(res "")
foreach(x ${my_list})
  set(res "${res}${x}\n")
endforeach()

message(STATUS "res:\n${res}")
---------------------------

One nice feature of this solution is that it does not rely on the fact that
a list is a semicolon-separated string.

When executing this using cmake -P nameOfScript.cmake, you will get the
following output:

---------------------------
-- my_list: alpha;beta;gamma
-- res:
alpha
beta
gamma
---------------------------

Sincerely,
    Anders Lindgren
