Yes.

That issue appears unrelated.  Did you typo the number?

Please also add the FIND_LIBRARY_USE_CUSTOM_SUFFIX item documentation,
or whatever it becomes after the discussion below.

Typically the FIND_LIBRARY_USE_LIB{32,64}_PATHS global properties
can be set by the platform information modules in CMake itself
on platforms that need the behavior.  In what context might the
FIND_LIBRARY_USE_CUSTOM_SUFFIX/LIB_SUFFIX values be set in practice?

Thanks,
