dear-imgui-example

Just a simple Dear ImGui + CMake + Conan setup.

Dependencies

Build Dependencies

• C++ compiler
• CMake
• Python (to create a venv for conan an optionally ninja)
• Conan Dependency Manager (installed via pip inside the venv)
• GLFW3 as a Window and Event Manager (conan dependency)
  • Note: this has a transitive dependency of opengl/system and conan install will probably try to install other transitive system dependencies, like libgl-dev and xorg-dev (at least on linux)
• Dear ImGui (conan dependency)

Build

# Creating venv for conan
python3 -m venv venv
. venv/bin/activate
pip install -U pip

# Installing conan pip dependency
pip install -r dev-requirements.txt

mkdir build && cd build

# Install conan dependencies for the specified build type
conan install .. -s build_type=Debug --build=imgui --build=glfw
# conan install .. -s build_type=Release --build=imgui --build=glfw

# Generate build files for your preferred build system
cmake .. -G Ninja
# cmake .. -G "Unix Makefiles"
# cmake .. -G "Visual Studio 15 2017 Win64"

# Build it
ninja
# make

Run

./bin/dear-imgui-conan-cmake-template
