The CMakeLists.txt file in the root folder is used to configure include directories and dependencies for building projects based on async_mqtt5. It does not define any build targets. It does, however, define BUILD_EXAMPLES macro which will generate project for an example. Therefore, please do not run the following command:

cmake -G "Visual Studio 17 2022" -A x64 -B bin64 -DCMAKE_TOOLCHAIN_FILE=C:/vcpkg/scripts/buildsystems/vcpkg.cmake -DVCPKG_CHAINLOAD_TOOLCHAIN_FILE="C:/Users/vinnie/src/boost/libs/http_proto/cmake/toolchains/msvc.cmake"

If you'd like to generate .vcxproj files for the included examples, you can do so by running:

cmake -G "Visual Studio 17 2022" -A x64 -B bin64 -DBUILD_EXAMPLES=ON

This will get you .vcxproj that you’ve expected.
