I'm actually using the ExternalProject_Add command of CMake to download and build boost, which I think is cloning and checking out the given commit:

Performing download step (git clone) for 'Boost'
1>  Cloning into 'boost'...
1>  Note: checking out '5ec478a570bdc71c5d4854e7165a8b3f4fa82ad9'.

1>  You are in 'detached HEAD' state. You can look around, make experimental
1>  changes and commit them, and you can discard any commits you make in this
1>  state without impacting any branches by performing another checkout.
1>
1>  If you want to create a new branch to retain commits you create, you may

1>
1>    git checkout -b <new-branch-name>
1>
1>  HEAD is now at 5ec478a... Update uuid from master

After that it is registering all submodules:

1>  Submodule 'accumulators' (https://github.com/boostorg/accumulators.git) registered for path 'libs/accumulators'
1>  Submodule 'algorithm' (https://github.com/boostorg/algorithm.git) registered for path 'libs/algorithm'
1>  Submodule 'align' (https://github.com/boostorg/align.git) registered for path 'libs/align'
1>  Submodule 'any' (https://github.com/boostorg/any.git) registered for path 'libs/any'
1>  Submodule 'array' (https://github.com/boostorg/array.git) registered for path 'libs/array'
1>  Submodule 'asio' (https://github.com/boostorg/asio.git) registered for path 'libs/asio'
1>  Submodule 'assert' (https://github.com/boostorg/assert.git) registered for path 'libs/assert'
1>  Submodule 'assign' (https://github.com/boostorg/assign.git) registered for path 'libs/assign'
1>  Submodule 'atomic' (https://github.com/boostorg/atomic.git) registered for path 'libs/atomic'
1>  Submodule 'bimap' (https://github.com/boostorg/bimap.git) registered for path 'libs/bimap'
........
1>  Submodule 'quickbook' (https://github.com/boostorg/quickbook.git) registered for path 'tools/quickbook'

and then it starts cloning the submodules:
1>  Cloning into 'libs/accumulators'...
1>  Submodule path 'libs/accumulators': checked out 'd022c85123683138ebec9149f0dc9aec6f3839cf'

1>  Cloning into 'libs/align'...
1>  Submodule path 'libs/align': checked out '0d6e14e133c47f11e81aa8e9f331da1d7ce7ad71'
1>  Cloning into 'libs/any'...

....
1>  Submodule path 'libs/container': checked out '5e3e5d4fe6b7ca88d1e1b32d302b7261d8313dc5'
1>  Cloning into 'libs/context'...

But if fails to clone libs/context apparently.

Thanks.

It's in the repo, but it's not on the master branch (at least in my
local copy, github is down at the moment). How are you cloning? If
you're only fetching the master branch for submodules then you won't
have the commit.
