The standard library componentstd::enable_ifallows for creating a substitution failure in order to enable or disable particular overloads based on a condition evaluated at compile time. In addition, manytype traitsmust be implemented with SFINAE if appropriate compiler extensions are unavailable. ...

Putting"compilerPath": ""(empty string) will skip querying a compiler. This is useful if a specified compiler doesn't support the arguments that are used for the query, as the extension will default back to any compiler it can find (like Visual C). Leaving out thecompilerPathproperty does...
