[PATCH] D72109: [cmake] Use relative cmake binary dir for processing pass plugins

[Michał Górny via Phabricator via llvm-commits]

mgorny added a comment.

This broke standalone build of clang. It's trying to write into `/include` (as in, root directory) now! My guess is that `LLVM_BINARY_DIR` is undefined at this point of standalone build, later it might be defined to point to directory where LLVM was installed which also wouldn't be correct.

   * ACCESS DENIED:  mkdir:        /include
  CMake Error at /usr/lib/llvm/11/lib64/cmake/llvm/AddLLVM.cmake:894 (file):
    file failed to open for writing (No such file or directory):
  
      /include/llvm/Support/Extension.def.tmp
  Call Stack (most recent call first):
    CMakeLists.txt:867 (process_llvm_pass_plugins)
