# library is enabled by setting LLVM_BUILD_LLVM_DYLIB=yes on the CMake

# commandline. By default the shared library only exports the LLVM C API.

# You can configure which libraries from LLVM you want to include in the shared

# library by setting LLVM_DYLIB_COMPONENTS to a semi-colon delimited list of

# LLVM components. All compoenent names handled by llvm-config are valid.
