Create separate package configuration files "LLVMConfig.cmake" for the LLVM build and install trees so that each can have information specific to its tree. Configure each with the corresponding include, lib, and cmake directories. Include the "LLVM-Config" API modules directly from the configured cmake modules directory. In the install tree, compute the installation prefix relative to the file location. In the build tree, provide information specific to the build tree for use by tools like Clang that can build externally against the LLVM build tree. Prefix such values in "LLVM_BUILD_" and comment them as such. Contributed by Brad King. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@201048 91177308-0d34-0410-b5e6-96231b3b80d8
