# In the absence of fine grained tablegen dependencies we need to ensure that
# Swift's libraries all build after the LLVM & Clang tablegen-generated headers
# are generated. When building out-of-tree (as with build-script) LLVM & Clang's
# CMake configuration files create these targets as dummies so we can safely
# depend on them directly here.
# See https://github.com/apple/swift/issues/48583.
#
# LLVM_COMMON_DEPENDS is a construct from the LLVM build system. It is a special
# purpose variable that provides common dependencies for all libraries, and
# executables generated when it is set. CMake's scoping rules enforce that these
# new dependencies will only be added to targets created under Swift's lib
# directory.

# Create a library that depends on all tool headers defined in include/module.modulemap
#
# TODO: generate this dynamically through the modulemap; this cannot use `sed`
# as that is not available on all platforms (e.g. Windows).
