# Add an interface library definition that is dependent on the source.
#
# It's probably easiest to explain why this macro exists, by describing
# what things would look like if we didn't have this macro.
#
# Let's suppose we want to statically link against torch. We've defined
# a library in cmake called torch, and we might think that we just
# target_link_libraries(my-app PUBLIC torch). This will result in a
# linker argument 'libtorch.a' getting passed to the linker.
#
# Unfortunately, this link command is wrong! We have static
# initializers in libtorch.a that would get improperly pruned by
# the default link settings. What we actually need is for you
# to do -Wl,--whole-archive,libtorch.a -Wl,--no-whole-archive to ensure
# that we keep all symbols, even if they are (seemingly) not used.
#
# What caffe2_interface_library does is create an interface library
# that indirectly depends on the real library, but sets up the link
# arguments so that you get all of the extra link settings you need.
# The result is not a "real" library, and so we have to manually
# copy over necessary properties from the original target.
#
# (The discussion above is about static libraries, but a similar
# situation occurs for dynamic libraries: if no symbols are used from
# a dynamic library, it will be pruned unless you are --no-as-needed)
