Dockcross manylinux ITK Remote Module Builds

[CavRiley]

On the python build scripts branch, the current script to build modules with dockcross (here) does not work with the changes to the branch. This is because it still is dependent on scripts that have been removed to clean up the codebase and needs to be reworked to work with the updated versions of the scripts. This includes refactoring script location to remove the internal directory and find an alternative to the scripts:

• dockcross-manylinux-build-module-deps.sh
• manylinux-aarch64-build-module-wheels.sh

Documentation also needs to be updated to reflect these changes in both the README.md and official ITKPythonPackage readthedocs here

@hjmjohnson are we still relying on the oneTBB library for remote module builds?

Also, do you know if the tools directory created during the build process is used for this library:

ITKPythonPackage/scripts/dockcross-manylinux-build-module-wheels.sh

Line 35 in f8ce642

HOST_MODULE_TOOLS_DIR=${HOST_MODULE_DIRECTORY}/tools

# Set up paths and variables for build
HOST_MODULE_TOOLS_DIR=${HOST_MODULE_DIRECTORY}/tools
mkdir -p  ${HOST_MODULE_TOOLS_DIR}
chmod 777 ${HOST_MODULE_TOOLS_DIR}

@hjmjohnson Using manylinux, I have been able to build a wheel for Cuberille and I can import the module into a python script as shown below but get an error when trying to access a filter. It may be due to caudate not having the required package

import itk

print(itk.Cuberille)
# <module 'Cuberille'>

print(itk.CuberilleImageToMeshFilter())
# Traceback (most recent call last):

I found online this may fix this problem but I'm unsure

sudo apt-get update
sudo apt-get install libtbb12

@hjmjohnson please disregard this. I found the issue within the linux_build_python_instance.py file. During the post_build_fixup step, the regex to find the wheels was incorrect so none of the itk proper wheels were 'fixed up' to include the required libtbb library.
