Install MySQL with headers and libraries, assumed to be in c:\mysql (some option in the installer like docs and includes, you should have the dir c:\mysql\include)

for error
========== Build: 1 succeeded, 4 failed, 0 up-to-date, 0 skipped ==========

In my case I forgot to add the additional installation files when installing MYSQL. Reinstall mysql and either repair or fresh install then choose to install the dev stuff, this will populate the include folder.
