[CMake] How to use FindPackageHandleStandardArgs

[Marcel Loose]

Hi Denis,

I think I understand what's going wrong.
I collect the *values* from the variables returned by find_library() in
XXX_LIBRARIES, not the names of these variables.

So, instead of passing LIB1 LIB2 LIB3 to
find_package_handle_standard_args() I'm actually passing ${LIB1} ${LIB2}
${LIB3}, which is, of course, quite different.

What's the best way to proceed. Should I collect the names of variables
used in the find_library() calls in a separate list variable and use
that for find_package_handle_standard_args(), or should I just handle
the REQUIRED and QUIET stuff myself in this case. Any recommendations?

Best regards,
Marcel Loose.
