# The Swift compiler depends on all the overlays and libraries for the Swift
# compiler.  These are version-matched with Swift.

# TARGET_DIR is where the lldb framework/shared library gets put.
# LLVM_BUILD_DIR is where LLVM and Clang got built
# LLVM_BUILD_DIR/lib/clang should exist and contain headers
