Can't include DirectX headers in VS2015

Question

I am trying to set up DirectX in my C++ project in Visual Studio 2015.

I have DirectX SDK installed in D:\Program Files (x86)\DirectX SDK, and my environment variable is called DXSDK_DIR.

In Visual Studio, I tried to add it to C/C++ --> General --> Additional Include Directories in all of the following ways:

$(DXSDK_DIR)\Include

%(DXSDK_DIR)\Include%

%"(DXSDK_DIR)\Include"%

%(DXSDK_DIR)%\Include

but none of them seemed to work.

Answer 1

For some reason, the environment variable's value is not D:\Program Files (x86)\DirectX SDK, as I expected, but only D:\Program Files (x86).

So, I guess the solution is to modify the environment variable so that it points to the DirectX SDK folder, and in Visual Studio add

%DXSDK_DIR%\Include

in C/C++ --> General --> Additional Include Directories

and

%DXSDK_DIR%\Lib

in Linker --> General --> Additional Library Directories.
