  <p>I am getting the following error on running any cmake commands</p>
  <p>'''
  CMake Deprecation Warning at CMakeLists.txt:5 (cmake_minimum_required):
  Compatibility with CMake &lt; 2.8.12 will be removed from a future version of
  CMake.</p>
  <p>Update the VERSION argument  value or use a ... suffix to tell
  CMake that the project does not need compatibility with older versions.</p>

  The CMAKE_C_COMPILER:</p>
  <pre><code>cl
  </code></pre>
  <p>is not a full path and was not found in the PATH.</p>
  <p>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).</p>
  <p>Tell CMake where to find the compiler by setting either the environment
  variable &quot;CC&quot; 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.</p>
