Configuration variables
|

-----------------------
|

|

By default, pybind11 will compile modules with the C++14 standard, if available
|
||||
on the target compiler, falling back to C++11 if C++14 support is not
|
||||
available. Note, however, that this default is subject to change: future
|
||||
pybind11 releases are expected to migrate to newer C++ standards as they become
|
||||
available. To override this, the standard flag can be given explicitly in
|
||||
`CMAKE_CXX_STANDARD <https://cmake.org/cmake/help/v3.17/variable/CMAKE_CXX_STANDARD.html>`_:
|
||||
By default, pybind11 will compile modules with the compiler default or the
|
||||
minimum standard required by PyBind11, whichever is higher. You can set the
|
||||
standard explicitly with
|
||||
`CMAKE_CXX_STANDARD <https://cmake.org/cmake/help/latest/variable/CMAKE_CXX_STANDARD.html>`_:

Note that this and all other configuration variables must be set **before** the
