# The chdir is needed because within numpy there's an `import signal`
# statement, and we don't want that to pick up scipy's signal module rather
# than the stdlib module. The try-except is needed because when things are
# split across drives on Windows, there is no relative path and an exception
# gets raised. There may be other such cases, so add a catch-all and switch to
# an absolute path. Relative paths are needed when for example a virtualenv is
# placed inside the source tree; Meson rejects absolute paths to places inside
# the source tree.
# For cross-compilation it is often not possible to run the Python interpreter
# in order to retrieve numpy's include directory. It can be specified in the
# cross file instead:
# [properties]
# numpy-include-dir = /abspath/to/host-pythons/site-packages/numpy/core/include
#
# This uses the path as is, and avoids running the interpreter.
