"error: Recursion in main target references" when upgrading to 1.76.0

[autoantwort]

In vcpkg every boost lib is its own lib, so we do not clone the boost meta repo recursively and build the whole thing. Every lib is cloned and build separately (outside of the boost tree).

One problem is that some libs like nowide imports files from outside the repository like here
Until now it was possible to workaround that by changing the import location and copying the necessary files:

file(READ "${SOURCE_PATH}/build/Jamfile.v2" _contents)
string(REPLACE "import ../../config/checks/config" "import config/checks/config" _contents "${_contents}")
string(REPLACE "check-target-builds ../config//cxx11_moveable_fstreams" "check-target-builds ../check_movable_fstreams.cpp" _contents "${_contents}")
string(REPLACE "check-target-builds ../config//lfs_support" "check-target-builds ../check_lfs_support.cpp" _contents "${_contents}")
file(WRITE "${SOURCE_PATH}/build/Jamfile.v2" "${_contents}")
file(COPY "${CURRENT_INSTALLED_DIR}/share/boost-config/checks" DESTINATION "${SOURCE_PATH}/build/config")
file(COPY "${SOURCE_PATH}/config/check_lfs_support.cpp" "${SOURCE_PATH}/config/check_movable_fstreams.cpp" DESTINATION "${SOURCE_PATH}/build/config")

But now with boost build 1.76.0 we get the following error:

Do you have an idea how to fix that or what has been chaneg that causes the recursion now?

Commit 95c875b breaks it. Before this commit the build is successful, after this commit it is no longer successful.

Thank you for your contributions. Main development of B2 has moved to https://github.com/bfgroup/b2
This issue has been automatically marked as "transition" to indicate the potential for needing transition to the new B2 development project.
