pybind11Config.cmake
|
|
--------------------
|
|
|
|
PYBIND11 cmake module.
|
|
This module sets the following variables in your project::
|
|
|
|
pybind11_FOUND - true if pybind11 and all required components found on the system
|
|
pybind11_VERSION - pybind11 version in format Major.Minor.Release
|
|
pybind11_VERSION_TYPE - pybind11 version type (dev, release)
|
|
pybind11_INCLUDE_DIRS - Directories where pybind11 and python headers are located.
|
|
pybind11_INCLUDE_DIR - Directory where pybind11 headers are located.
|
|
pybind11_DEFINITIONS - Definitions necessary to use pybind11, namely USING_pybind11.
|
|
pybind11_LIBRARIES - compile flags and python libraries (as needed) to link against.
|
|
pybind11_LIBRARY - empty.
|
|
|
|
|
|
Available components: None
|
|
|
|
|
|
Exported targets::
|
|
|
|
If pybind11 is found, this module defines the following :prop_tgt:`IMPORTED`
|
|
interface library targets::
|
|
|
|
pybind11::module - for extension modules
|
|
pybind11::embed - for embedding the Python interpreter
|
|
|
|
Python headers, libraries (as needed by platform), and the C++ standard
|
|
are attached to the target.
|
|
|
|
Advanced targets are also supplied - these are primary for users building
|
|
complex applications, and they are available in all modes::
|
|
|
|
pybind11::headers - Just the pybind11 headers and minimum compile requirements
|
|
pybind11::pybind11 - Python headers too
|
|
pybind11::python_link_helper - Just the "linking" part of pybind11:module, for CMake < 3.15
|
|
pybind11::python2_no_register - Quiets the warning/error when mixing C++14+ and Python 2, also included in pybind11::module
|
|
pybind11::thin_lto - An alternative to INTERPROCEDURAL_OPTIMIZATION
|
|
pybind11::lto - An alternative to INTERPROCEDURAL_OPTIMIZATION (also avoids thin LTO on clang)
|
|
pybind11::windows_extras - Adds bigobj and mp for MSVC
|
|
|
|
Modes::
|
|
|
|
There are two modes provided; classic, which is built on the old Python
|
|
discovery packages in CMake, or the new FindPython mode, which uses FindPython
|
|
from 3.12+ forward (3.15+ _highly_ recommended).
|
|
|
|
New FindPython mode::
|
|
|
|
To activate this mode, either call ``find_package(Python COMPONENTS Interpreter Development)``
|
|
before finding this package, or set the ``PYBIND11_FINDPYTHON`` variable to ON. In this mode,
|
|
you can either use the basic targets, or use the FindPython tools::
|
|
|
|
find_package(Python COMPONENTS Interpreter Development)
|
|
find_package(pybind11 CONFIG)
|
|
|
|
# pybind11 method:
|
|
pybind11_add_module(MyModule1 src1.cpp)
|
|
|
|
# Python method:
|
|
Python_add_library(MyModule2 src2.cpp)
|
|
target_link_libraries(MyModule2 pybind11::headers)
|
|
set_target_properties(MyModule2 PROPERTIES
|
|
INTERPROCEDURAL_OPTIMIZATION ON
|
|
CXX__VISIBILITY_PRESET ON
|
|
VISIBLITY_INLINES_HIDDEN ON)
|
|
|
|
If you build targets yourself, you may be interested in stripping the output
|
|
for reduced size; this is the one other feature that the helper function gives you.
|
|
|
|
Classic mode::
|
|
|
|
Set PythonLibsNew variables to influence python detection and
|
|
CMAKE_CXX_STANDARD to influence standard setting. ::
|
|
|
|
find_package(pybind11 CONFIG REQUIRED)
|
|
|
|
# Create an extension module
|
|
add_library(mylib MODULE main.cpp)
|
|
target_link_libraries(mylib PUBLIC pybind11::module)
|
|
|
|
# Or embed the Python interpreter into an executable
|
|
add_executable(myexe main.cpp)
|
|
target_link_libraries(myexe PUBLIC pybind11::embed)
|
|
|
|
Suggested usage::
|
|
|
|
find_package with version info is not recommended except for release versions. ::
|
|
|
|
find_package(pybind11 CONFIG)
|
|
find_package(pybind11 2.0 EXACT CONFIG REQUIRED)
|
|
|
|
|
|
The following variables can be set to guide the search for this package::
|
|
|
|
pybind11_DIR - CMake variable, set to directory containing this Config file
|
|
CMAKE_PREFIX_PATH - CMake variable, set to root directory of this package
|
|
PATH - environment variable, set to bin directory of this package
|
|
CMAKE_DISABLE_FIND_PACKAGE_pybind11 - CMake variable, disables
|
|
find_package(pybind11) when not REQUIRED, perhaps to force internal build
|
|
|
|
Helper functions::
|
|
|
|
pybind11_add_module(...) - Add a library and setup all helpers
|
|
pybind11_strip(target) - Strip a target after building it (linux/macOS)
|
|
pybind11_extension(target) - Injects the Python extension name
|
|
|
|
See ``pybind11Tools.cmake`` or ``pybind11NewTools.cmake`` for details on
|
|
``pybind11_add_module``.
