 # libIREECompiler.so building
 # It's 2023. We were supposed to have sane ways to build shared libraries.
 # We were promised.
 #
 # Anyway, the shared library must be explicitly assembled from the *object
 # libraries* that make up its public interface. We could use the new
 # $<LINK_LIBRARY:WHOLE_ARCHIVE> feature to bypass this old way of doing it,
 # but that interacts badly with BUILD_SHARED_LIBS mode (since it would then
 # not be linking the static libraries *into* a composite shared library).
 #
 # Therefore, we duplicate the object libs from above. They are lexically
 # related:
 #   1. LLVM derived object libraries are named with an "obj." prefix.
 #   2. IREE derived object libraries are named with an ".objects" suffix.
 #   3. Alias libraries don't work, so we need to use the "_" vs "::" form.
 #
 # Given this variance, we opt for simple duplication. Make sure that the list
 # below is always kept in sync with the list above for StaticImpl.
 #
 # Further, we have to separate out the LINK_LIBRARIES dependencies of the
 # OBJECTS libraries and include them manually as PRIVATE deps of the shared
 # library. This involves some generator shenanigans.
 #
 # Finally, we allow super-projects to export additional API from our shared
 # library by populating the IREE_COMPILER_API_ADDL_EXPORT_OBJECTS.
