CPACK_NSIS_EXTRA_PREINSTALL_COMMANDS is empty unless the user provide
some value for it.

CPACK_NSIS_FULL_INSTALL is populated with "File /r
\"${INST_DIR}\\*.*\" unless the
user provide another value.

which corresponds to the source code default behavior.

I am no NSIS expert so I can't imagine why 'File /r "${INST_DIR}\*.*"'
could possibly do ???

So I guess that if your template does not contain such command you
either need it
(and should use CPACK_NSIS_FULL_INSTALL in your template) or replace
it with something more appropriate to you case.

Now on the semantic,

CPACK_NSIS_FULL_INSTALL probably means "full install of all components"

you will find other CPACK_NSIS_*_COMPONENTS* var

CPACK_NSIS_INSTALLER_MUI_COMPONENTS_DESC
CPACK_NSIS_PAGE_COMPONENTS
CPACK_NSIS_COMPONENT_SECTIONS
CPACK_NSIS_COMPONENT_SECTION_LIST
...

See http://www.cmake.org/Wiki/CMake:Component_Install_With_CPack
for some explanation about component vs full/monolithic install with CPack.
