+
+    Revert to use add_llvm_library and revert linking LLVM libraries (#438)
+    
+    Add cmake option EXCLUDE_LIBS_FROM_ALL to remove a specific llvm library
+    from llvm 'all'.
+    
+    This PR partially reverts 743bd15.
+    This PR addresses #401, #417, #418, #422, and brings back SONAME.
