Could NOT find PythonLibs
报错：
CMake Error at /usr/share/cmake-3.22/Modules/FindPackageHandleStandardArgs.cmake:230 (message):
Could NOT find PythonLibs (missing: PYTHON_LIBRARIES PYTHON_INCLUDE_DIRS)
Call Stack (most recent call first):
/usr/share/cmake-3.22/Modules/FindPackageHandleStandardArgs.cmake:594 (_FPHSA_FAILURE_MESSAGE)
/usr/share/cmake-3.22/Modules/FindPythonLibs.cmake:310 (FIND_PACKAGE_HANDLE_STANDARD_ARGS)
CMakeLists.txt:5 (find_package)
一句话原因：find_package(PythonLibs, …)这种方式在CMake 3.12版本及之后废弃了，相应的诸如PYTHON_LIBRARIES这些变量也都不存在了，所以使用CMake 3.12以上版本会报该错误。
解决办法：用find_package(Python3 COMPONENTS Interpreter Development)替代find_package(PythonLibs, …)和find_package(PythonInterp, …)
原因详述：CMake3.20文档中找到FindPythonLibs，显示如下信息：Deprecated since version 3.12: Use FindPython3, FindPython2 or FindPython instead，再到FindPython3查看怎样引用python库及头文件
fatal error: Python.h: No such file or directory
一句话原因：target_include_directories(${TARGET} PRIVATE ${Python3_INCLUDE_DIR}) 中使用了Python3_INCLUDE_DIR而不是Python3_INCLUDE_DIRS
解决办法：将Python3_INCLUDE_DIR替换为Python3_INCLUDE_DIRS即可
原因详述：在FindPython3中有Python3_INCLUDE_DIR：The path to the directory of the Python headers. It will be used to compute the variable Python3_INCLUDE_DIRS.就直接拿来用了，结果报找不到python.h的头文件
