blob: 4516ebe0ee7d0c7a0d3556515f27cb4d361d3736 (plain) (tree)























                                                                                   
Fix LLVMConfig.cmake being generated to use correct LLVM_INSTALL_PREFIX
(e.g. /usr/lib/llvm5).

This is needed e.g. for building lldb.
