In case that any of the input variables that hold the library names contains
more than just a single library the "debug" or "optimized" keywords were only
prepended to the first item, making all other libs appear in all
configurations. Just treat both input variables as lists.
Thanks to Philipp Berger <newsletters@philippberger.de> for pointing me at
this.
If the debug and release libraries are the same (which usually means only one
of them was found) do not output the library as "optimized" and "debug", but
just as one plain library. At the end this means that the Find* output of the
avarage (Un*x) user will be much less cluttered.
This adds copyright/license notification blocks CMake's non-find
modules. Most of the modules had no notices at all. Some had notices
referring to the BSD license already. This commit normalizes existing
notices and adds missing notices.
