# macOS 26 (Tahoe) moved libc++ headers inside the SDK; Apple clang 17 no longer
# finds them at the old search path. This causes boring-sys's cmake step to fail
# when building with --features stealth. Setting CXXFLAGS and SDKROOT here makes
# them visible to all build scripts (including boring-sys's) so cmake can locate
# the headers. force=false lets CI or developers override via their shell env.
# Non-macOS platforms ignore SDKROOT; the -isystem path is silently skipped if
# it doesn't exist. See: https://github.com/h4ckf0r0day/obscura/issues/136
