# Note: We can't use the Boost::library targets in the configure checks as they may not yet be included
# by the superproject when this CMakeLists.txt is included. We also don't want to hardcode include paths
# of the needed libraries and their dependencies, recursively, as this is too fragile and requires maintenance.
# Instead, we collect include paths of all libraries and use them in the configure checks. This works faster
# if there is a unified Boost include tree in the filesystem (i.e. if `b2 headers` was run or we're in the
# official monolithic Boost distribution tree).
