Don't know but it would be an interesting feature even if
in my case I would prefer to chose the set of packages with
a kind of "subproject" or "subpackage" and not one package for one install.

Nevertheless I don't know if CMake+CPack support this but it
seems doable as custom CMake MACROs set.

Don't know.

We use NSIS installer without the trouble you seems to have,
could you tell us what are "the variables you'd think it would use"?

Do you
INCLUDE(CPack)
BEFORE or AFTER
setting your custom CPACK_xxx variables?

If you look at CPack.cmake you'll see that some variables
(if not all) are defined by CPack.cmake iff they were not defined:

>>>
cpack_set_if_not_set(CPACK_NSIS_DISPLAY_NAME
"@CPACK_PACKAGE_INSTALL_DIRECTORY@")
>>>
