How to build

1. Make sure cmake is installed.
2. Make sure Vulkan SDK and glfw3 and glm is installed. I used vcpkg to manage the packages. Make sure glslc is present and is in the PATH variable.
3. Create a directory call "build".
4. Run cd build && cmake .. <options>
5. If using Makefile or NMake, run make vkTest or nmake vkTest. Otherwise, with MSBuild, msbuild <output sln file> -target:vkTest
