// different target platforms) but it also exposes the whole ImGui source for inspection, which can be pretty handy.
// Source files are included from Third Party directory, so we can wrap them in required by Unreal Build System headers
// without modifications in ImGui source code.

// We don't need to define IMGUI_API manually because it is already done for this module.
