Cmake Fehler bei der Installation von dlib unter Windows?

Question

Ich versuche, dlib-19.2 in Windows 7 zu installieren. Aber während des Aufbaus von dlib bekomme ich diese Fehler.

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.

Kann jemand mir den Grund des Fehlers erklären und wie it.Cmake GUI scheint zu funktionieren völlig in Ordnung zu vermeiden.
