cmMakefile: Add missing initializer for recently added member

In commit 2f1ffa003c (find_package: Add support for default GLOBAL
imported targets, 2022-03-10) we added a field without an initializer.
This was exposed by a few failures in nightly testing.  Previously it
worked only by chance that the member's memory had suitable values.
