Subject: [PATCH] build: Allow building Cling using the Clang shared library.
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.
