"""setup for the dlib project
Copyright (C) 2015 Ehsan Azar (dashesy@linux.com)
License: Boost Software License See LICENSE.txt for the full license.
This file basically just uses CMake to compile the dlib python bindings project
located in the tools/python folder and then puts the outputs into standard
python packages.
To build the dlib:
python setup.py build
To build and install:
python setup.py install
To package the wheel (after pip installing twine and wheel):
python setup.py bdist_wheel
To upload the binary wheel to PyPi
twine upload dist/*.whl
To upload the source distribution to PyPi
python setup.py sdist upload
To exclude/include certain options in the cmake config use --yes and --no:
for example:
--yes USE_AVX_INSTRUCTIONS: will set -DUSE_AVX_INSTRUCTIONS=yes
--no USE_AVX_INSTRUCTIONS: will set -DUSE_AVX_INSTRUCTIONS=no
Additional options:
--compiler-flags: pass flags onto the compiler, e.g. --compiler-flag "-Os -Wall" passes -Os -Wall onto GCC.
--clean: delete any previous build folders and rebuild. You should do this if you change any build options
by setting --compiler-flags or --yes or --no since last time you ran a build to make sure the changes
take effect.
