[llvm-dev] can't build/run after adding lib to Fibonacci example, even reverting the complete llvm tree does not help

Fri Sep 21 10:20:27 PDT 2018

I might try compiling your source from the VS's Developer Command Prompt:

cmake --build . --target Fibonacci

Does this work?

Otherwise, there might be some workarounds. E.g. Unload the
"ZERO_CHECK" project from the IDE so it does not reconfigure (or just
run cmake from outside the IDE before building). Or start the IDE from
the Developer Command Prompt so the right environment variables are
set.
