vs2022 快速搭建imgui工程
vcpkg.exe install imgui[imgui:x64-windows]:x64-windows-static
vcpkg.exe install imgui[docking-experimental]:x64-windows-static
vcpkg install imgui[dx11-binding]:x64-windows-static
vcpkg install imgui[win32-binding]:x64-windows-static
vcpkg.exe integrate install
因为安装的是static 静态库，需要vs2022设置vcpkg开启static

Color definitions in ImGui are a good starting point,
but do not cover all the intricacies of Spectrum's possible colors
in controls and widgets.
One big difference is that ImGui communicates widget activity
(hover, pressed) with their background, while spectrum uses a mix
of background and border, with border being the most common choice.
Because of this, we reference extra colors in spectrum from
imgui.cpp and imgui_widgets.cpp directly, and to make that work,
we need to have them defined at here at compile time.
