# 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,-lz 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.
