Using 3.2785.1473.gc7e062b on Windows, FindCEF.cmake includes cef_variables.cmake, which gives you a USE_SANDBOX option - but it straight away makes a decision about command line options based on its value, giving you no obvious way of changing it! So, if you want to build with VS2015, but don't want to use the sandbox... how do you do that? It looks like it isn't possible, but hopefully that's just a hole in my cmake knowledge...
(Regardless of whether building without the sandbox is a good idea or not, I still want at least the option of a proper debug build, that links with the debug runtime libraries.)
For now I've gone back to 3.2743.1449.g90ba67d.
Thanks,
