DirectX vectors and matrices

To configure the VC + + directory for vs2013 project properties:

For example, the DirectX SDK installation directory is the D:\Program Files (x86) \microsoft DirectX SDK (June 2010)

The Include directory and library directories are configured as follows:

/* Include */
$ (Vc_includepath); $ (Windowssdk_includepath);D: \program Files%28x86%29\microsoft DirectX SDK%28june 2010%29\include
/* Lib */
$ (vc_librarypath_x86); $ (windowssdk_librarypath_x86);D: \program Files%28x86%29\microsoft DirectX SDK%28june 2010%29 \lib\x86;$ (LibraryPath)

You can use LIB to add or use preprocessing Directives #pragma comment (Comment-type, ["commentstring"]) in the project properties-linker-input-additional dependencies.
