library. Installs tblgen (required by Clang). Translates handling of user settings and platform-dependant options to its own file, where it can included by another project. Installs the .cmake files required by projects like Clang. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@124816 91177308-0d34-0410-b5e6-96231b3b80d8
