Absolutely, positively do NOT use GLOB for project build chains or for
header or source discovery.
There are well documented reasons not to do this. You must express the
dependency chain in
linear order in libs/CMakeLists.txt.

I would have the boostorg/CMakeLists.txt call:

add_subdirectories ( libs )
after it has included all the things libs depends on.

Then have libs/CMakeLists.txt call add_subdirectories in dependency order.
That is the only way you can reasonably ensure a linear dependency chain.
