ERROR: LoadError: could not load library "libLLVM-8.0.1"

[ouening]

OS: Ubuntu18.04
Julia: 1.4.1

When I planed to install Cxx，I encountered error:

ERROR: LoadError: could not load library "libLLVM-8.0.1"
│ libLLVM-8.0.1.so: cannot open shared object file: No such file or directory

I found that :

julia> using Base

julia> Base.lib
libblas_name              libllvm_version_string
liblapack_name            libm_name
libllvm_version           library_threading_enabled
julia> Base.libllvm_version
v"8.0.1"

In directory lib/julia there has libLLVM.so and libSSVM-8jl.so，I think the problem is the version of LLVM doesn't satisfy the requirement, as shown in LINE 23 in ~/.julia/packages/Cxx/1RaOv/deps/build.jl，can someone tell how to fix it?

dup of #464. you could either downgrade Julia to 1.3.x or wait for #465.
