How can I programmatically force the compiler to stop the compilation process after it encountered a user created error?

Question

In my code I am using the #error preprocessor directive in order to create an error. However, it still continues the building process.

How can I force the building process programmatically to stop after encountering my error?

I am using Microsoft Visual Studio 2015, C++ v140, x86, for Windows 10.

I am specifically searching a solution to do this `programmatically`. — Michiel Pater, Oct 21 '15 at 15:23
What do you mean by *programmatically*? In the code? Via external scripting? — Kninnug, Oct 21 '15 at 15:28
Something like `#stop` to stop compiling after a certain `#if` statement was true. Not using a plugin for Visual Studio. — Michiel Pater, Oct 21 '15 at 15:31

@cad: OP knows about `#error` and also isn't asking about GCC. — cremno, Oct 21 '15 at 15:41
`#error` is exactly meant for this. Could you be more specific in what is happening to your build? — Jens Gustedt, Oct 21 '15 at 15:47
`#error` terminates compilation of the current translation unit (source file). It doesn't necessarily stop an IDE from continuing to compile other sources files. — Keith Thompson, Oct 21 '15 at 16:27

The #error directive emits a user-specified error message at compile time and then terminates the compilation.

(Emphasis Added)

If compilation is continuing after the #error directive, then you're doing something odd, or MSVC is broken.
