Running CHISEL with customized LLVM & Clang locations

[Mohannadcse]

I'm trying to build CHISEL from source, but I don't want to install LLVM on my machine, instead, I downloaded the binary and source of Clang and LLVM (I didn't build LLVM from source). I exported the paths to LLVM and Clang into the .bashrc file. As shown below.

However, I'm still I can't build CHISEL and cmake keeps complaining about not finding the path to LLVM_CONFIG_EXECUTABLE

I also was experiencing this blocker, but passing the config executable path into cmake manually worked for me. Inside the build directory I created after cloning the repo I ran:

cmake -DLLVM_CONFIG_EXECUTABLE=<path to llvm-config> ..
