4 # PYBIND11 cmake module.
5 # This module sets the following variables in your project::
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.
18 # Available components: None
23 # If pybind11 is found, this module defines the following :prop_tgt:`IMPORTED`
24 # interface library targets::
26 # pybind11::module - for extension modules
27 # pybind11::embed - for embedding the Python interpreter
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. ::
34 # find_package(pybind11 CONFIG REQUIRED)
35 # message(STATUS "Found pybind11 v${pybind11_VERSION}: ${pybind11_INCLUDE_DIRS}")
37 # # Create an extension module
38 # add_library(mylib MODULE main.cpp)
39 # target_link_libraries(mylib pybind11::module)
41 # # Or embed the Python interpreter into an executable
42 # add_executable(myexe main.cpp)
43 # target_link_libraries(myexe pybind11::embed)
47 # find_package with version info is not recommended except for release versions. ::
49 # find_package(pybind11 CONFIG)
50 # find_package(pybind11 2.0 EXACT CONFIG REQUIRED)
53 # The following variables can be set to guide the search for this package::
55 # pybind11_DIR - CMake variable, set to directory containing this Config file
56 # CMAKE_PREFIX_PATH - CMake variable, set to root directory of this package
57 # PATH - environment variable, set to bin directory of this package
58 # CMAKE_DISABLE_FIND_PACKAGE_pybind11 - CMake variable, disables
59 # find_package(pybind11) when not REQUIRED, perhaps to force internal build
