Cmake 无法找到 PythonLibs。

Question

我正在尝试按照这个教程在Windows上为Vim下载YouCompleteMe。在调用CMake时：

cmake -G "Visual Studio 14 Win64" -DPATH_TO_LLVM_ROOT=%USERPROFILE%/ycm_temp/llvm_root_dir . %USERPROFILE%/vimfiles/bundle/YouCompleteMe/third_party/ycmd/cpp

它抛出以下异常：

CMake Error at C:/Program Files/CMake/share/cmake-3.9/Modules/FindPackageHandleStandardArgs.cmake:137 (message):
Could NOT find PythonLibs (missing: PYTHON_LIBRARIES PYTHON_INCLUDE_DIRS)
(Required is at least version "2.6")
Call Stack (most recent call first):
C:/Program Files/CMake/share/cmake-3.9/Modules/FindPackageHandleStandardArgs.cmake:377 (_FPHSA_FAILURE_MESSAGE)
C:/Program Files/CMake/share/cmake-3.9/Modules/FindPythonLibs.cmake:262 (FIND_PACKAGE_HANDLE_STANDARD_ARGS)
CMakeLists.txt:189 (find_package)

我已经安装了Python-2.7.13，并将其放在“环境变量”中的“PATH”下。

我应该怎么做才能修复这个异常？

不要使用：

cmake -G "Visual Studio 14 Win64" -DPATH_TO_LLVM_ROOT=%USERPROFILE%/ycm_temp/llvm_root_dir . %USERPROFILE%/vimfiles/bundle/YouCompleteMe/third_party/ycmd/cpp

您应该将DPYTHON_INCLUDE_DIR和DPYTHON_LIBRARY标志设置为以下内容：

-DPYTHON_INCLUDE_DIR=C:\Python27\include \
-DPYTHON_LIBRARY=C:\Python27\libs

如果您使用默认安装路径（C:\Python27），完整的命令如下所示：

cmake -G "Visual Studio 14 Win64" -DPATH_TO_LLVM_ROOT=%USERPROFILE%/ycm_temp/llvm_root_dir . %USERPROFILE%/vimfiles/bundle/YouCompleteMe/third_party/ycmd/cpp -DPYTHON_INCLUDE_DIR=C:\Python27\include -DPYTHON_LIBRARY=C:\Python27\libs
