Do NOT set CPACK_PACKAGE_INSTALL_REGISTRY_KEY unless you really need a value
for it different than the default.

Please look at the definition of this variable in Modules/CPack.cmake. Its
default value is set like this:

cpack_set_if_not_set(CPACK_PACKAGE_INSTALL_REGISTRY_KEY

  "${CPACK_PACKAGE_NAME} ${CPACK_PACKAGE_VERSION}")

The value is supposed to be a simple string, not a full reg key path. In the
NSIS template file, it's used to save some information about the
installation into the registry when the end user runs the installer. But the
usage of the value @CPACK_PACKAGE_INSTALL_REGISTRY_KEY@ in the NSIS template
file assumes that value may be used as a sub-key *already* under the "blah
blah/SOFTWARE/this/that" root key.

Do not try to use a full registry key path as the
CPACK_PACKAGE_INSTALL_REGISTRY_KEY.

What are you trying to do by setting this? Let us know, maybe somebody will
have a useful suggestion.


HTH,
David
