Building

Without package managers

Dependencies are built from sources. Provide paths to required libraries source code:

• glad: -DGLAD_PREFIX="/path/to/glad/generated"
• GLFW: -DGLFW_PREFIX="/path/to/glfw"
• Dear ImGui: -DDEAR_IMGUI_PREFIX="/path/to/dearimgui"

By default these paths are set to _dependencies/LIBRARY-NAME (so you can copy those there).

$ cd /path/to/glfw-imgui-example
$ mkdir build && cd $_
$ cmake -G Ninja -DCMAKE_BUILD_TYPE=Release \
    -DCMAKE_INSTALL_PREFIX="../install" \
    -DUSING_CONAN=0 \
    ..
$ cmake --build . --target install
$ ../install/bin/glfw-imgui/glfw-imgui

With Conan

Pre-built dependencies are fetched from Conan server, only the application itself is built from sources.

Without using CMake preset:

$ cd /path/to/glfw-imgui-example
$ mkdir build && cd $_
$ conan install .. --remote=YOUR-CONAN-REMOTE
$ cmake -G Ninja -DCMAKE_BUILD_TYPE=Release \
    -DCMAKE_INSTALL_PREFIX="../install" \
    -DUSING_PACKAGE_MANAGER_CONAN=1 \
    ..
$ cmake --build . --target install

Using CMake preset:

$ cd /path/to/glfw-imgui-example
$ mkdir build/conan && cd $_
$ conan install ../.. -r YOUR-CONAN-REMOTE
$ cd ../..
$ cmake --preset conan
$ cmake --build --preset conan

More information about resolving dependencies with Conan here.

With vcpkg

Preparation:

• you need to have vcpkg installed;
  • its executable is available in the PATH;
  • VCPKG_ROOT environment variable is set;
• to be able to use CMake presets v3, you need to have CMake at least v3.21.

Without using CMake preset:

$ cd /path/to/glfw-imgui-example
$ mkdir build && cd $_
$ cmake -G Ninja -DCMAKE_BUILD_TYPE=Release \
    -DCMAKE_INSTALL_PREFIX="../install" \
    -DUSING_PACKAGE_MANAGER_VCPKG=1 \
    -DCMAKE_TOOLCHAIN_FILE="$VCPKG_ROOT/scripts/buildsystems/vcpkg.cmake" \
    ..
$ cmake --build . --target install

Using CMake preset:

$ cd /path/to/glfw-imgui-example
$ cmake --preset vcpkg-default-triplet
$ cmake --build --preset vcpkg-default-triplet
