# Upstream pulls every one of these with FetchContent at configure time, which
# is not allowed here, so they are fetched as distfiles and redirected with
# FETCHCONTENT_SOURCE_DIR_*. StormLib and tinycc are only used when
# INCLUDE_MPQ_SUPPORT or ENABLE_SCRIPTING are on, and libgfxd only when
# GFX_DEBUG_DISASSEMBLER is, so none of the three are needed here.
