The Debian release of NumPy 2 and later comes with improved Multi-Arch support
for binary Python extensions:
1. `pkg-config numpy --cflags` works out of the box. There is no need to
set PKG_CONFIG_PATH as documented in the reference manual.
If you want to remain compatible with other distributions, we recommend
overriding PKG_CONFIG_PATH only if necessary, e.g.,
: "${PKG_CONFIG:=pkg-config}"
if ! $PKG_CONFIG --exists numpy; then
export PKG_CONFIG_PATH=$(numpy-config --pkgconfigdir)
fi
2. numpy-config and `numpy.get_include()` query the MULTIARCH configuration
variable from the sysconfig module. For cross builds, set the
_PYTHON_SYSCONFIGDATA_NAME environment variable, e.g.
export _PYTHON_SYSCONFIGDATA_NAME=_sysconfigdata__${DEB_HOST_ARCH_OS}_${DEB_HOST_MULTIARCH}
