Before anything else I'm trying to compile and install libobjc2-1.8...
cd to the unpacked libobjc dir and then do:
abort with the following error:
CMake Error at opts/CMakeLists.txt:4 (include):
include could not find load file:
CMake Error at opts/CMakeLists.txt:11 (add_llvm_loadable_module):
Unknown CMake command "add_llvm_loadable_module".
I'm running Clang 3.9 and llvm 3.9 for over a year having not such error.
