Buildroot: CMake Error at /home/gabriel/repos/my_repo/output/board/host/share/cmake-3.25/Modules/FindPackageHandleStandardArgs.cmake:230 (message): Could NOT find Boost (missing: thread) (found version "1.80.0")
I'm trying to build a host-ros-cpp-common package in Buildroot for an embedded Linux board, containing the contents of this folder here: https://github.com/ros/roscpp_core/tree/noetic-devel/cpp_common
I'm building that folder above at version tag 0.5.8, actually: https://github.com/ros/roscpp_core/tree/0.5.8/cpp_common
I'm building on Ubuntu 22.04 with gcc-11, migrating from Ubuntu 18.04 with gcc-8. Any idea how to solve this error? Also, what does (missing: thread) mean?:

I recently upgraded the Boost package to the latest from Buildroot, here: https://github.com/buildroot/buildroot/tree/master/package/boost, because boost itself was failing to build on my new build system of gcc-11 and Ubuntu 22.04 prior to doing that.
I also opened an issue about this here: https://github.com/ros/roscpp_core/issues/134
And I left a comment here: https://github.com/ethz-asl/kalibr/issues/566#issuecomment-1376788400
My research attempts:
Update: I think the problem has something to do with this CMake line, but I don't know CMake: https://github.com/ros/roscpp_core/blob/0.5.8/cpp_common/CMakeLists.txt#L4:
find_package(Boost REQUIRED COMPONENTS system thread)
After 1 hr of research and trial and error...
My host is the build machine, which is Ubuntu 22.04. It is building stuff for my host (host-ros-cpp-common), and therefore needs the Boost libs for my host. So, the buildroot target (for the embedded Linux ARM-core device) boost package I just upgraded has nothing to do with my host I think! It's for the target. So, the solution appears to be to simply install libboost-thread-dev onto Ubuntu 22.04, which is my host. The package libboost-all-dev, contains libboost-thread-dev plus more, so just install that instead:
sudo apt update
sudo apt install libboost-all-dev
Now make gets past that previous error and onto the next one!
That must be it!
