Pass options to `build_ext`

[diegoferigo]

It not clear to me (and I didn't find much documentation) whether is possible to pass extra options to the build_ext.

The help output print the following:

  --config-setting CONFIG_SETTING, -C CONFIG_SETTING
                        pass options to the backend.  options which begin with a hyphen must be in the form of "--config-setting=--opt(=value)" or "-C--opt(=value)"

But I couldn't find how to use it properly for this purpose.

In comparison, this is how the same can be done using other systems:

python setup.py bdist_wheel build_ext -D"BAR=Foo;VAR=TRUE"
pip wheel --global-option="build_ext" --global-option="-DBAR=Foo;VAR=TRUE" .

setuptools doesn't properly support config settings. You could try python -m build -C--global-option=build_ext -C--global-option=-DBAR=Foo;VAR=TRUE.

I was looking for exactly something like what you suggested, it seems working fine! Thanks for the prompt answer. Closing.
