Yes there is a variable with this name defined in CPack.cmake and used
by CPack executable...but....

it is not documented :-(
(this may be worth a bug report/feature request)

basically if CPACK_MODULE_PATH is not defined by the user
then cpack does;

set(CPACK_MODULE_PATH ${CMAKE_MODULE_PATH})

then CPack uses
CPACK_MODULE_PATH.

If the template fits your needs you do not need to do anything beside
defining the appropriate value for CPACK_NSIS_xxx variable in your
CMakeLists.txt.

If you need more then following what's writtent there
http://www.cmake.org/Wiki/CMake:CPackNSISAdvancedTips
seems OK to me.

In your project source tree then modify
CPACK_MODULE_PATH or CMAKE_MODULE_PATH in order
to make CPack find yours before the one provided by CMake.
