指令行 cmake 指定 python 路徑

指令行 cmake 指定 python 路徑(這裡寫自定義目錄标題)

指令行 cmake

cmake .. \
-DPYTHON_INCLUDE_DIR=$(python -c "from distutils.sysconfig import get_python_inc; print(get_python_inc())")  \
-DPYTHON_LIBRARY=$(python -c "import distutils.sysconfig as sysconfig; print(sysconfig.get_config_var('LIBDIR'))")
           

cmake 指定變量的格式是

-D<VARIABLE>{:<TYPE>}=<VALUE>
           

例如，給 FILEPATH 類型的變量 PYTHON_LIBRARIES 指派 “C:/Python35/libs/python35.lib” 的代碼為：

-DPYTHON_LIBRARIES:FILEPATH=C:/Python35/libs/python35.lib
           

上述 cmake 利用 python 解釋器傳回的資訊填充了參數值，是最可靠的，無需手工輸入。

Thus, the trick is to fill those parameters with the returned information from the python interpreter, which is the most reliable. This may work independently of your python location/version (also for Anaconda users)
