vcpkg与cmake

可使用vcpkg作为包管理

• 在运行cmake命令时，指定vcpkg的目录即可。如cmake .. -G "Visual Studio 15 Win64" -DCMAKE_TOOLCHAIN_FILE=D:/software/vcpkg/scripts/buildsystems/vcpkg.cmake

  if(NOT CMAKE_TOOLCHAIN_FILE)
  message(
    FATAL_ERROR
      "Please set CMAKE_TOOLCHAIN_FILE with <yourlocal>/vcpkg/buildsystems/vcpkg.cmake."
  )
  endif()
