"""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 repackage the previously built package as wheel (bypassing build):
python setup.py bdist_wheel --repackage
To install a develop version (egg with symbolic link):
python setup.py develop
To exclude/include certain options in the cmake config use --yes and --no:
for example:
--yes DLIB_NO_GUI_SUPPORT: will set -DDLIB_NO_GUI_SUPPORT=yes
--no DLIB_NO_GUI_SUPPORT: will set -DDLIB_NO_GUI_SUPPORT=no
Additional options:
--compiler-flags: pass flags onto the compiler, e.g. --compiler-flag "-Os -Wall" passes -Os -Wall onto GCC.
--debug: makes a debug build
--cmake: path to specific cmake executable
--G or -G: name of a build system generator (equivalent of passing -G "name" to cmake)
