Building libcef_dll_wrapper
---------------------------

libcef_dll_wrapper needs to be compiled with /MD, otherwise you get linker errors
of type "already defined". When you try to compile using /MD you may get warnings:

  warning C4275: non dll-interface class 'stdext::exception' used as base for
  dll-interface class 'std::bad_typeid' see declaration of 'stdext::exception'
  see declaration of 'std::bad_typeid'

Which results in build errors. To solve it you need to add command line option:

  -D_HAS_EXCEPTIONS=1

Enabling C++ exceptions ("/EHsc") is not required.
