ya thats pretty much it
to give some more detail, im using a SDK which has the following layout:
e:\\somesdk\\contrib\\boost
e:\\somesdk\\contrib\\xxx
e:\\somesdk\\include
e:\\somesdk\\include\\xxx
e:\\somesdk\\include\\yyy
e:\\somesdk\\include\\zzz
so i did smth like this:
set SOMESDK=e:\\somesdk\\include
set SOMESDK_CONTRIB=e:\\somesdk\\contrib
in source code i do:
#include <xxx/some.h>
#include <yyy/some.h>
#include <boost/some.h>
btw you dont need to reboot for testing. you can open e.g. a cmd prompt, set the env vars and start vs from there or you make a batch
dont forget to rebuild db:)
