Yep, those two are never going to work. The CMakeLists.txt in those
directories aren't self-contained.

> cmake -G Ninja -DLLVM_ENABLE_PROJECTS="clang;lli;llc" ../llvm  this command which resulted in the build directory getting loaded with many subdirectories including tools directory containing lli and llc. But still it didn't enable lli and llc even after mentioning it in the ENABLE_PROJECTS flag

You don't need lli or llc in LLVM_ENABLE_PROJECTS because they're part
of baseline LLVM. But other than that it should have worked. What
error message did you get when you tried running "ninja llc" after
that CMake command?

Cheers.
