ccls: dyld: Library not loaded: @rpath/libLLVM.dylib

[casouri (Yuan Fu)]

ccls-clang-8.0 doesn't work. When I run ccls(soft-linked from ccls-clang-8.0)

dyld: Library not loaded: @rpath/libLLVM.dylib
  Referenced from: /opt/local/bin/ccls
  Reason: image not found
zsh: abort      ccls

is printed.

Well heck -- I was sure we had this fixed finally. Let me look into that.

I see, this is not in the clang-X build itself, but uses clang.

It will probably need a similar fix to what we did in clang-8.0 for example, I would think:

# clang shared libraries are not all installed in ${cmake.install_prefix}/lib
# so we have to let the llvm/clang cmake scripts handle the @rpath setting
# See:
#     https://llvm.org/bugs/show_bug.cgi?id=31425
#     https://trac.macports.org/ticket/53299
configure.args-delete \
    -DCMAKE_INSTALL_NAME_DIR=${cmake.install_prefix}/lib \
    -DCMAKE_INSTALL_RPATH=${cmake.install_prefix}/lib \
    -DCMAKE_SYSTEM_PREFIX_PATH="${prefix}\;/usr"
configure.args-append \
    -DCMAKE_SYSTEM_PREFIX_PATH="${cmake.install_prefix}\;${prefix}\;/usr"
