I guess not all NSIS specific variables are documented, but you can
find a list of var
there:
http://www.cmake.org/cmake/help/v2.8.8/cpack.html#section_VariablesspecifictoCPackNSISgenerator

If you use CPack 2.8.X then

cpack --help-variable CPACK_NSIS_MUI_ICON

will give you the documentation of the concerned variable (if there is some).

Not me.
May be you can have a look into Source/CPack/cmCPackNSISGenerator.cxx.

>From what you say I guess replacing the NSIS template is the way to go.
In order to know what you can expect to be filled in by CPack
you should review the list of generic CPACK_xx variables and the list
of CPACK_NSIS_xxx variable:
http://www.cmake.org/cmake/help/v2.8.8/cpack.html#section_Variables
Those variable may be used in your custom template.

Beware that the NSIS generator uses 2 customizable files:
NSIS.template.in
and
NSIS.InstallOptions.ini.in

both files are "configured" by the generator.
