Add SYSTEM to target_include_directories in vendored CMake wrappers and set INTERFACE_SYSTEM_INCLUDE_DIRECTORIES on imported / sub-project targets so warnings from third-party headers no longer surface in our build output. Introduces a mark_target_includes_system() helper in cmake/utils.cmake (resolves aliases, skips missing targets) used by the upstream-add_subdirectory wrappers (glog, gflags, googletest, yaml-cpp, protobuf, antlr).

# CRoaring v2.0.4 - integrated as a single-file amalgamation build.
|
|
#
|
|
# We deliberately do NOT pull the upstream repository as a git submodule
|
|
# anymore: it ships ~292M of benchmarks/test data that we never build, which
|
|
# made `git submodule update --init --recursive` painfully slow and bloated
|
|
# the local checkout.
|
|
#
|
|
# Instead, the official amalgamation produced by CRoaring's release pipeline
|
|
# (https://github.com/RoaringBitmap/CRoaring/releases/tag/v2.0.4) is checked
|
|
# into CRoaring-2.0.4/:
|
|
#
|
|
# CRoaring-2.0.4/roaring.c - single C TU containing the entire library
|
|
# CRoaring-2.0.4/roaring.h - public C API (from official release)
|
|
# CRoaring-2.0.4/roaring.hh - public C++ wrapper (from official release)
|
|
# CRoaring-2.0.4/roaring64map.hh - 64-bit C++ wrapper (from cpp/ in tarball)
|
|
# CRoaring-2.0.4/include/roaring/roaring.h
|
|
# - identical to roaring.h, exposed under the
|
|
# historical <roaring/roaring.h> path so
|
|
# existing callers keep working.
|
|
#
|
|
# To upgrade, replace these files with the assets from a newer release tag
|
|
# (and grab cpp/roaring64map.hh from the source tarball if it is still split).
