How can I ignore the header file in the same directory where source code is, which includes the header and use the other header in different path

Question

At first, my project tree is as below

project/main.c
project/Test.h
project/Test/Test.h

In "main.c",

include "Test.h"

Currently, "Test.h" in "main.c" refers to project/Test.h because Visual Studio finds the included header first in the same directory where source code including the header is.
I want to fix that "Test.h" in "main.c" refers to project/Test/Test.h without any modification of source code.

Is there any solution for this?

Hi @성진 김 ,

Welcome to Microsoft Q&A!

If you don’t want to edit your code, you can right click on your project in the Solution Explorer > choose “Properties" > VC++ Directories > Include Directories > Add your include directories.

Sincerely,

To avoid having the preprocessor search for included headers in the same location as the source file the #include directive should use angle brackets instead of quotations. The details of how the preprocessor searches are discussed in hash-include-directive-c-cpp
