When more than one value is given to the NAMES option this command by
default will consider one name at a time and search every directory
for it.  The NAMES_PER_DIR option tells this command to consider one
directory at a time and search for all names in it.

If the library found is a framework, then VAR will be set to the full
path to the framework <fullPath>/A.framework.  When a full path to a
framework is used as a library, CMake will use a -framework A, and a
-F<fullPath> to link the framework to the target.

If the global property FIND_LIBRARY_USE_LIB64_PATHS is set all search
paths will be tested as normal, with "64/" appended, and with all
matches of "lib/" replaced with "lib64/".  This property is
automatically set for the platforms that are known to need it if at
least one of the languages supported by the PROJECT command is
enabled.
