cross-project-tests/CMakeLists.txt

# Cross project tests, for tests that require access to multiple projects across
# LLVM (e.g. clang, lld and lldb).
# The subset inside debuginfo-tests invoke clang to generate programs with
# various types of debug info, and then run those programs under a debugger
# such as GDB or LLDB to verify the results.
