ImGuizmo example app that uses cmake and vcpkg

Assuming cmake and vcpkg are installed, all that is required is to add the vcpkg toolchain file to the cmake configure and all dependencies will be downloaded and installed into the project

mkdir build
cd build
cmake .. -DCMAKE_TOOLCHAIN_FILE=C:/dev/vcpkg/scripts/buildsystem/vcpkg.cmake

Rather than running directly, IDEs usually configure the cmake. Visual studio can be integrated directly with the vcpkg integrate install command or by specifying the path to the toolchain file in the project cmake settings

When using the cmake tools extension the command can be added to the .vscode/settings.json file as follows

{
    "cmake.configureArgs": [
        "-DCMAKE_TOOLCHAIN_FILE=C:\\dev\\vcpkg\\scripts\\buildsystems\\vcpkg.cmake"
    ]
}

✔️ If you include the settings file in your repo, a good practice would be to use an environment variable for the path to the vcpkg install and variable substitution in the toolchain file path so the settings work across machines. eg "-DCMAKE_TOOLCHAIN_FILE={$env:VCPKG_ROOT}\\scripts\\buildsystems\\vcpkg.cmake"

This can also be added to the system-wide settings rather than added to each project individually

The example contains a vcpkg.json manifest file that contains the dependencices. When cmake is supplied with the vcpkg toolchain file, the script detects this manifest file and then downloads and compiles the dependencies there-in

In CMakeLists.txt the find_package(imguizmo CONFIG REQUIRED) command finds the cmake config added by the vcpkg install and target_link_libraries(example-app PRIVATE imguizmo::imguizmo) adds the includes and lib to the target
