# With the CMAKE_MSVC_RUNTIME_LIBRARY=MultiThreaded option [1], we
# tell cmake to compile lexbor static library with /MT flag, which
# means it will statically link the C runtime library. For the NIF
# library, we compile with /LD flag (to produce .dll), which implies
# /MT by default [2]. It is important that both link the same C
# runtime library, otherwise there are conflicts on startup.
