Hi Asiri,
Did you fix the issue when building libcxx and libcxxabi use LLVM's
libunwind?

I experienced the similar issue:
CMake Error at projects/libcxxabi/src/CMakeLists.txt:163
(target_link_libraries):
Target "unwind" of type UTILITY may not be linked into another
target. One
may link only to INTERFACE, OBJECT, STATIC or SHARED libraries, or to
executables with the ENABLE_EXPORTS property set.
