# In this file, for stdlib source embed and stdlib embed itself, we define two
# targets, one which includes the embed and one which does not, these are
# linked in as needed to libslang and libslang-without-embedded-stdlib (for
# slang-bootstrap)
#
# If MSVC supported weak linking we could just have a single library for each
# and just not link it if we didn't want the embed...
