Fix the Cmake command to build LLVM in Developers' documentation about clad HOT 3 CLOSED

Hi Rishabh,
Thank you for opening the issue.
The following build instructions should work:

sudo -H pip install lit
git clone https://github.com/llvm/llvm-project.git
cd llvm-project
git checkout release/12.x
cd ../
mkdir obj inst
cd obj
cmake ../llvm-project/llvm -DCMAKE_BUILD_TYPE=Debug -DLLVM_TARGETS_TO_BUILD=host -DLLVM_ENABLE_PROJECTS=clang -DCMAKE_INSTALL_PREFIX=../inst
make install

The instructions were missing a cd command.

Thanks for the reply @parth-07 I was able to build llvm by keeping obj and inst inside the llvm-project and by changing ../llvm-project/llvm to ../llvm but your solution seems to be a better; should I submit a PR making the changes you suggested ? .

Yes, sure.
Thank you for being proactive.
