如何使用cmake查找jupyter notebook安装？

Question

有没有办法使用cmake find_package()来定位jupyter_notebook安装？

我试过了

FIND_PACKAGE(jupyter-notebook REQUIRED)

但是它错误地输出了

CMake Error at CMakeLists.txt:15 (FIND_PACKAGE):
  By not providing "Findjupyter-notebook.cmake" in CMAKE_MODULE_PATH this
  project has asked CMake to find a package configuration file provided by
  "jupyter-notebook", but CMake did not find one.

  Could not find a package configuration file provided by "jupyter-notebook"
  with any of the following names:

    jupyter-notebookConfig.cmake
    jupyter-notebook-config.cmake

  Add the installation prefix of "jupyter-notebook" to CMAKE_PREFIX_PATH or
  set "jupyter-notebook_DIR" to a directory containing one of the above
  files.  If "jupyter-notebook" provides a separate development package or
  SDK, be sure it has been installed.


-- Configuring incomplete, errors occurred!

但是，它已被安装：

apt-cache show jupyter-notebook

使用find_package命令、MODULE和CONFIG时，有几个选项。对于这种情况，您可能需要CONFIG设置。错误消息试图在这里提供帮助。这些文件是否随jupyter-notebook安装一起提供？

jupyter-notebookConfig.cmake
jupyter-notebook-config.cmake

如果是这样，请尝试将CMAKE_PREFIX_PATH或jupyter-notebook_DIR设置为jupyter-notebook的安装目录。因此，您可以尝试执行以下操作：

list(APPEND CMAKE_PREFIX_PATH /path/to/your/installation) # Try this one.
# SET(jupyter-notebook_DIR /path/to/your/installation) # Or try this one.
FIND_PACKAGE(jupyter-notebook CONFIG REQUIRED)

如果您的安装似乎没有前面提到的CMake配置文件，也没有任何CMake支持文件( cmake目录等)，那么find_program命令可能更适合jupyter-notebook。

我建议花一些时间使用find_package的documentation，因为它显式地列出了CMake用来查找包的搜索路径(按顺序)。另外，请查看此answer。
