I'm trying to build an openthread border router using buildroot for a beaglebone black, and I'm facing the following error:
CMake Error: The inter-target dependency graph contains the following strongly connected component (cycle):
"openthread-ftd" of type SHARED_LIBRARY
depends on "tcplp-ftd" (weak)
"tcplp-ftd" of type STATIC_LIBRARY
depends on "openthread-ftd" (weak)
At least one of these targets is not a STATIC_LIBRARY. Cyclic dependencies are allowed only among static libraries.
CMake Generate step failed. Build files cannot be regenerated correctly.
make: *** [package/pkg-generic.mk:273: /var/home/joshuajohn/Workspaces/Legion/buildroot/output/build/openthread-thread-reference-20230710/.stamp_configured] Error 1
I've configured buildroot to build both shared and static libraries, and both these libraries come from the openthread border router submodules. I'm using the same configurations provided by openthread for beaglebone (in examples/platforms/beagleboneblack/default.) I'm using cmake with ninja as the backend and building the binaries like the supported method does, so this issue has me stumped.
What could be causing this issue? I understand that openthread recommends using their setup script to setup openthread, but I'm using this as an exercise to deepdive into buildroots build systems. Please let me know if more information is required.

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by switching back to a branch.
If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -c with the switch command. Example:
git switch -c <new-branch-name>
Or undo this operation with:

I wasn't sure how to fix this, since I saw target_link_libraries and assumed that the project used shared libraries as well. I looked into building it with static libraries and came across this github issue. The solution is to pass -DBUILD_SHARED_LIBS=OFF to the cmake options.
