# When we have updated static libraries in competition with older

|
|
# 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.
