Hardcopy of pybind11 instead of using git submodules (#552)
* removed pybind as submodule * added hardcopy of pybind11 2.10.0 * rename pybind11 folder to avoid conflicts when changing branch Co-authored-by: Dhanya Thattil <dhanya.thattil@psi.ch>

# - Find python libraries
|
||||
# This module finds the libraries corresponding to the Python interpreter
|
||||
# FindPythonInterp provides.
|
||||
# This code sets the following variables:
|
||||
#
|
||||
# PYTHONLIBS_FOUND - have the Python libs been found
|
||||
# PYTHON_PREFIX - path to the Python installation
|
||||
# PYTHON_LIBRARIES - path to the python library
|
||||
# PYTHON_INCLUDE_DIRS - path to where Python.h is found
|
||||
# PYTHON_MODULE_EXTENSION - lib extension, e.g. '.so' or '.pyd'
|
||||
# PYTHON_MODULE_PREFIX - lib name prefix: usually an empty string
|
||||
# PYTHON_SITE_PACKAGES - path to installation site-packages
|
||||
# PYTHON_IS_DEBUG - whether the Python interpreter is a debug build
|
||||
#
|
||||
# Thanks to talljimbo for the patch adding the 'LDVERSION' config
|
||||
# variable usage.
