This is a convenient template for quickly getting a cross-platform GUI project up and running in C++ with GLFW, OpenGL, and DearImGUI.
Create a build directory
mkdir build && cd build
Run CMake from the build directory
cmake ..
To build and execute the project, use the generated makefile (Unix default) or MSBuild solution (Windows default).
To add header and source files, append the filepaths to add_executable(${PROJECT_NAME} main.cpp <your_files_here>)
To modify the user interface, see the ImGUI GLFW/OpenGL example, or uncomment the ImGui::ShowDemoWindow() function in main.cpp.
For convenience, ImPlot, ImSpinner, and LegitProfiler are also included in the ImGui source files.
If your application does not require rendering outside of the UI itself, you can set bUIShouldFillWindow = true to in main.cpp. This will force the ImGUI context to fill the GLFW window.
Otherwise, you can use the GLFW window to render arbitrary geometry, with floating ImGUI windows that can be dragged or docked for convenience. ImGUI will generate an imgui.ini file in the build directory, which stores layout preferences, and automatically sets ImGUI window positions and sizes on startup. Delete this file to reset preferences to default.
