The wheel package must be installed.

notice the install --user so your user site package must be in path etc... python -m site --user-site

Also In your trace I can see py38-or-tools-9.1 so I suppose you want use python3.8 ? but the end of the command line we could see /usr/local/bin/python3.10 setup.py bdist_wheel

note1: To find Python 3 we use the cmake built-in module FindPython3 -> https://cmake.org/cmake/help/latest/module/FindPython3.html (which search for the most recent version)

Python3_FIND_STRATEGY New in version 3.15. This variable defines how lookup will be done. The Python3_FIND_STRATEGY variable can be set to one of the following: VERSION: Try to find the most recent version in all specified locations. This is the default if policy CMP0094 is undefined or set to OLD. LOCATION: Stops lookup as soon as a version satisfying version constraints is founded. This is the default if policy CMP0094 is set to NEW.

you should take a look at: https://cmake.org/cmake/help/latest/module/FindPython3.html#artifacts-specification

note2: on manylinux each python install is separated so we use -DPython3_ROOT_DIR="$1" https://github.com/google/or-tools/blob/86d4c543f717fa8716a9d66c25143660668bf825/tools/docker/python/build-manylinux.sh#L40-L47 ... https://github.com/google/or-tools/blob/86d4c543f717fa8716a9d66c25143660668bf825/tools/docker/python/build-manylinux.sh#L65-L66

There was confusion with multiple python versions. wheel was installed for python-3.8 and or-tools was discovering python-3.10.
