  4. # PYBIND11 cmake module.
  5. # This module sets the following variables in your project::
  6. #
  7. # pybind11_FOUND - true if pybind11 and all required components found on the system
  8. # pybind11_VERSION - pybind11 version in format Major.Minor.Release
  9. # pybind11_INCLUDE_DIRS - Directories where pybind11 and python headers are located.
  10. # pybind11_INCLUDE_DIR - Directory where pybind11 headers are located.
  11. # pybind11_DEFINITIONS - Definitions necessary to use pybind11, namely USING_pybind11.
  12. # pybind11_LIBRARIES - compile flags and python libraries (as needed) to link against.
  13. # pybind11_LIBRARY - empty.
  14. # CMAKE_MODULE_PATH - appends location of accompanying FindPythonLibsNew.cmake and
  15. # pybind11Tools.cmake modules.
  16. #

  18. # Available components: None

  25. #
  26. # pybind11::module - for extension modules
  27. # pybind11::embed - for embedding the Python interpreter
  28. #
  29. # Python headers, libraries (as needed by platform), and the C++ standard
  30. # are attached to the target. Set PythonLibsNew variables to influence
  31. # python detection and PYBIND11_CPP_STANDARD (-std=c++11 or -std=c++14) to
  32. # influence standard setting. ::
