CMake enhancements for automated external package building
Add explicit defaults where missing for clarity. Support passing in NETGEN_GIT_VERSION for use when building, eg, RPM packages using rpkg, which requires building from an untagged source bundle, that is, not directly from a git checkout. Add option to choose build against internal or external Pybind11; add cmake module to find and configure against system Pybind. re-add versioning of shared library files. Add section for GCC-specific options setting (right now, to turn off harmless warnings). Warn if pybind11_stubgen is not found. Adjust stubgen paths to work when build is not in-place in the source tree.

# 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
|
||||
#
