A simple app that lets you zoom into a visualization of the mandelbrot set. The zoom depth is limited by the accuracy of floating point numbers.

Build

I am not an expert on CMake, but the following works: Start in the project root directory

1. Clear build/

   rm -rf build

2. Run cmake while specifying release or debug configuration (Release or Debug)

   cmake -S . -B build -DCMAKE_BUILD_TYPE=Release

3. Build

   cmake --build build -- -j$(nproc)

4. Run the compiled binary from within the folder bin-Release/ or bin-Debug/

Build Options

These options are defined/checked by the cmake/ helper modules in the repo.

• -DCMAKE_BUILD_TYPE=<Debug|Release|RelWithDebInfo|MinSizeRel>

  • For single-config generators (Make/Ninja). Controls optimization, debug info and many helper generator-expressions.
  • Example: -DCMAKE_BUILD_TYPE=Release

• -DENABLE_CLANG_TIDY=ON|OFF (default: OFF)

  • If ON, CMake will attempt to find clang-tidy and attach it to the target using CXX_CLANG_TIDY.
  • In the project it is configured to run for the Debug config only (via a generator expression).
  • Requires clang-tidy to be installed on your PATH.

• Sanitizer options (these are read by cmake/Sanitizers.cmake) — set them at configure time:

  • -DENABLE_SANITIZER_ADDRESS=ON — enable AddressSanitizer (ASan) in Debug.

  • -DENABLE_SANITIZER_LEAK=ON — enable Leak sanitizer.

  • -DENABLE_SANITIZER_UNDEFINED_BEHAVIOR=ON — enable UBSan.

  • -DENABLE_SANITIZER_THREAD=ON — enable ThreadSanitizer (TSan) — incompatible with Address/Leak.

  • -DENABLE_SANITIZER_MEMORY=ON — MemorySanitizer (Clang only), incompatible with Address/Thread/Leak.

  • -DENABLE_COVERAGE=ON — enable coverage flags for gcc/clang (used for Debug).

  • Notes & rules:

    • Sanitizer flags are applied only to Debug builds (the project uses generator expressions so they don’t affect Release).
    • The helper emits warnings if you request incompatible sanitizer combinations (e.g. thread + address).

• -DCMAKE_INSTALL_PREFIX=/some/path

  • Used by cpack / cmake --install flows. Not required for development builds.

How the repository wiring works (brief)

I guess only relevant if one tries to fix a bug in the cmake setup.

• MandelbrotApp – the executable target.
• ImGuiLib – a static library target that builds the ImGui core + GLFW + OpenGL backends (imgui_impl_glfw.cpp, imgui_impl_opengl3.cpp).
• glad – a STATIC library built from lib/GLAD/glad.c. It provides GL function pointers and must be compiled with C enabled.
• ImGuiLib links glad as PUBLIC, so consumers of ImGuiLib automatically get glad transitively. The final executable links to ImGuiLib (and system libs).
• cmake/CompilerWarnings.cmake, cmake/Sanitizers.cmake, cmake/StaticAnalysis.cmake provide helper functions and options.
