There are a few possibilities to build Matplotlib on Windows:

* Wheels via `matplotlib-winbuild <https://github.com/jbmohler/matplotlib-winbuild>`_
* Wheels by using conda packages
* Conda packages
* Wheels by using conda packages (see below)
* Conda packages (see below)

Wheel builds using conda packages

The binary requirements (png, FreeType,...) are statically linked and therefore
not needed during the wheel install.

Set up the conda environment. Note, if you want a qt backend, add ``pyqt`` to
the list of conda packages.

The pytz dependency has been removed in #11360 and shouldn't be here.

activate matplotlib_build
# if you want a qt backend, you also have to install pyqt (be aware that pyqt doesn't mix well if
# you have created the environment with conda-forge already activated...)
conda install pyqt
# this package is only available in the conda-forge channel

msinttypes is now available via conda


# copy the libs which have "wrong" names
set LIBRARY_LIB=%CONDA_PREFIX%\Library\lib
mkdir lib || cmd /c "exit /b 0"
copy %LIBRARY_LIB%\zlibstatic.lib lib\z.lib
copy %LIBRARY_LIB%\libpng_static.lib lib\png.lib

# Make the header files and the rest of the static libs available during the build
# CONDA_DEFAULT_ENV is a env variable which is set to the currently active environment path
set MPLBASEDIRLIST=%CONDA_PREFIX%\Library\;.

# build the wheel
python setup.py bdist_wheel

The `build_alllocal.cmd` script in the root folder automates these steps if
you have already created and activated the conda environment.

New way of activating an environment is conda activate


For building, call the script ``build_alllocal.cmd`` in the root folder of the
repository::

build_alllocal.cmd
