- # When we have updated static libraries in competition with older
- # shared libraries and we want the former to win, we need to do some
- # extra work. The *_PRELOAD_ARCHIVES settings are invoked early
- # and will pull in the entire archive to the binary giving it
- # priority in symbol resolution. Beware of cmake moving the
- # achive load itself to another place on the link command line. If
- # that happens, you can try something like -Wl,-lpng16 here to hide
- # the archive. Also be aware that the linker will not tolerate a
- # second whole-archive load of the archive. See viewer's
- # CMakeLists.txt for more information.
