Changed WINSDK_INCLUDE_PATH & WINSDK_LIB_PATH variable to WindowsSdkDir.
Changed WINSDK_INCLUDE_PATH & WINSDK_LIB_PATH variable to WindowsSdkDir.

${WINSDK_INCLUDE_PATH} becomes ${WindowsSdkDir}/Include and
${WINSDK_LIB_PATH} becomes ${WindowsSdkDir}/Lib.

With this, there will be only one variable to be set (WindowsSdkDir).
Also, the new variable's name is the same one used in the actual MSVC
project, which makes the setting more congruent and easier to remember.

Also, its recommended to set the ${WindowsSdkDir} variable at the Build
Variables section instead of Environment Variables.
