在 Windows 上安装 dlib 期间出现 Cmake 错误？

Question

我正在尝试在 Window 7.But 中安装 dlib-19.2，但在 dlib 的构建过程中出现了这些错误。

Configuring cmake ...
-- Building for: NMake Makefiles
-- The C compiler identification is unknown
-- The CXX compiler identification is unknown
CMake Error in CMakeLists.txt:
  The CMAKE_C_COMPILER:
    cl
  is not a full path and was not found in the PATH.
  To use the NMake generator with Visual C++, cmake must be run from a shell
  that can use the compiler cl from the command line.  This environment is
  unable to invoke the cl compiler.  To fix this problem, run cmake from the
  Visual Studio Command Prompt (vcvarsall.bat).
  Tell CMake where to find the compiler by setting either the environment
  variable "CC" or the CMake cache entry CMAKE_C_COMPILER to the full path to
  the compiler, or to the compiler name if it is in the PATH.

任何人都可以向我解释错误的原因以及如何避免 it.Cmake GUI 似乎工作得很好。
