Please read the [general build guide](BUILD.md) for information on dependencies required for all platforms. Only Windows specific instructions are found in this file.
Interface can be built as 32 or 64 bit.
###Visual Studio 2013
You can use the Community or Professional editions of Visual Studio 2013.

###Qt
You can use the online installer or the offline installer. If you use the offline installer, be sure to select the "OpenGL" version.
NOTE: Qt does not support 64-bit builds on Windows 7, so you must use the 32-bit version of libraries for interface.exe to run. The 32-bit version of the static library is the one linked by our CMake find modules.

* Qt > Qt 5.5.1 > **msvc2013 32-bit**

Once Qt is installed, you need to manually configure the following:
* Set the QT_CMAKE_PREFIX_PATH environment variable to your `Qt\5.5.1\msvc2013\lib\cmake` directory.
* Set the QT_CMAKE_PREFIX_PATH environment variable to your `Qt\5.5.1\msvc2013\lib\cmake` or `Qt\5.5.1\msvc2013_64\lib\cmake` directory.
* You can set an environment variable from Control Panel > System > Advanced System Settings > Environment Variables > New
###External Libraries
As it stands, Hifi/Interface is a 32-bit application, so all libraries should also be 32-bit.
All libraries should be 32- or 64-bit to match your build preference.
CMake will need to know where the headers and libraries for required external dependencies are.
We use CMake's `fixup_bundle` to find the DLLs all of our exectuable targets require, and then copy them beside the executable in a post-build step. If `fixup_bundle` is having problems finding a DLL, you can fix it manually on your end by adding the folder containing that DLL to your path. Let us know which DLL CMake had trouble finding, as it is possible a tweak to our CMake files is required.

The recommended route for CMake to find the external dependencies is to place all of the dependencies in one folder and set one ENV variable - HIFI_LIB_DIR. That ENV variable should point to a directory with the following structure:

###Build High Fidelity using Visual Studio
Follow the same build steps from the CMake section of [BUILD.md](BUILD.md), but pass a different generator to CMake.
For 32-bit builds:
cmake .. -G "Visual Studio 12"
For 64-bit builds:
cmake .. -G "Visual Studio 12 Win64"
Open %HIFI_DIR%\build\hifi.sln and compile.
