[CMake] How to use FindPackageHandleStandardArgs

[Marcel Loose]

Hi Denis,

That's my case as well. I need to find more than one library, and it's
an all or nothing situation. I mean, if any of the libraries I'm
searching for is missing, the package as such cannot be used. So, my
original question still stands:

How should I pass a list of libraries to
find_package_handle_standard_args(), where one or more of the elements
of the list may be YYY-NOTFOUND?

Marcel.
