-Subject: [PATCH] build: Allow building Cling using the Clang shared library.
+Upstream status: https://github.com/root-project/root/pull/15563
-The officially supported way to build LLVM/Clang as a shared library
-is via the LLVM_BUILD_LLVM_DYLIB and LLVM_LINK_LLVM_DYLIB CMake
-options (see: https://llvm.org/docs/BuildingADistribution.html). When
-built this way, the whole of Clang API is exposed as a shared
-library (libclang-cpp.so).
-
-* CMakeLists.txt: Query if we're in shared mode via llvm-config, and
-register the result as LLVM_LIB_IS_SHARED.
-[LLVM_LIB_IS_SHARED] <target_link_libraries>: Use the PUBLIC interface of the
-LLVM shared library.
-* lib/Interpreter/CMakeLists.txt [LLVM_LIB_IS_SHARED]: When defined, replace the
-individual Clang components by clang-cpp.
-* lib/MetaProcessor/CMakeLists.txt: Likewise.
-* lib/Utils/CMakeLists.txt: Likewise.
-* tools/Jupyter/CMakeLists.txt: Likewise.
-* tools/driver/CMakeLists.txt: Likewise.
-* tools/libcling/CMakeLists.txt: Likewise.
