Update dependencies to latest versions.

[dkeeney]

Nearly all of the dependencies have significantly newer versions available.
We need to update the URL's from which to get the dependencies so that we are using more recent versions.

[dkeeney]

The following dependencies need to be updated:

• eigen to 3.4.0 math library (header only)
• googletest to 1.11.0 test environment (header only)
• pybind11 to 2.9.2 python to C++ binding library (header only)
• libyaml to 0.2.5, yaml parser (header only)
• cpp-httplib to 0.10.4, a REST server (header only)
• cereal to 1.3.2, serialization (header only)

dependency that do not need updating:

• Boost, We only use this with old compilers. So don't bother changing it.
• digestpp, No changes
• mnist data set. We don't want to change the baseline so keep data the same. It might be good to update the mnist driver software however. -- separate Issue.

I agree, we should bump these versions.

BTW: The MNIST data set does not ever change, its just the infrastructure that changes.

If you make the PR, I'd be happy to run a clean build & test on my platform: linux.

Ok, I will take you up on that.
We need a Mac to test with as well. Maybe I can setup a virtual Mac on my PC using VirtualBox.

I do have one problem where the de-pickle of everything found an incorrectly formatted Base64 encoded string causing the py unit tests to fail. (at bindings/py/tests/regions/network_test.py line 378). Just started to look at this. It would be helpful to know if this also happens on Linux.

I will check-in what I have so you can try it.

Hi,
Yes I get that error on linux (release mode):
E RuntimeError: Exception: RegisteredRegionImplPy.hpp(132) message: Error: Invalid base64-encoded string: number of data characters (65) cannot be 1 more than a multiple of 4

I was able to compile on OSX 12.3 with a just-now-cloned copy of htm.core. I had to remove the -Werror flag on line 282 of CommonCompilerConfig.cmake. python setup.py test returns this at the end:

Cool. Yes, I get the first two errors on windows building with all new versions except pybind11.
I assume you are using the latest master. So that means that these errors existed before my updates.

The third error in HtmRestApiTest that you received may be related to the Mac's network connections. That test tries to run two threads, one server and one client, and tries to make a connection between them.
