livepp provides CMake targets:

  find_package(unofficial-livepp CONFIG REQUIRED)
  target_link_libraries(main PRIVATE unofficial::livepp::livepp)

The macro LIVEPP_PATH is also set to point to the livepp installation folder and can be used to create agents:

  lpp::LppDefaultAgent lppAgent = lpp::LppCreateDefaultAgent(nullptr, L"" VCPKG_LIVEPP_PATH);
