Subject: CMake: Rely on llvm_config again for obtaining the list of required
X-Git-Url: http://plrg.eecs.uci.edu/git/?a=commitdiff_plain;h=8e3864f99c65a8f9c7221f732281275f238d71f4;p=oota-llvm.git

CMake: Rely on llvm_config again for obtaining the list of required
libraries for an executable.

Now LLVMConfig uses a new system for sorting library dependencies, as
the list of dependent libraries for each entry of FinalLibDeps.txt no
longer is topologically sorted.
