I did what you suggested, I added COMPILE_ALL_D_FILES_AT_ONCE=OFF 
and removed memset.d from the build and now the first build goes 
through.

I thought memset.d was kind of strange as this was something that 
could obviously be mitigated to LLVM. Shouldn't this be removed 
from the build in the cmake file?

Thank you.
