Build Fails Due to Missing LLVM Config and Header Files, and CMake Project Command Issue

[zaimingli]

Issue Description

When attempting to build the project, the script fails due to multiple issues related to LLVM configuration and CMake settings:

1. LLVM Configuration Issue:
   The llvm-config script is not found, indicating that LLVM may not be installed or is not in the system's PATH
   ../build.sh: 1: llvm-config: not found
2. Include Header Error:
   The file llvm/Pass.h cannot be found which halts the compilation of main.cpp:./src/main.cpp:6:10: fatal error: llvm/Pass.h: No such file or directory
   6 | #include "llvm/Pass.h"
   | ^~~~~~~~~~~~~
   compilation terminated.

Expected Behavior

The build script should complete without errors, successfully compiling all modules.

Actual Behavior

The build process fails due to missing LLVM configuration and header file issues. Additionally, a CMake configuration warning is issued.

Possible Solutions

• Ensure LLVM is correctly installed and llvm-config is accessible in your PATH.
• Verify the presence of llvm/Pass.h in your LLVM installation directory, or ensure the correct LLVM version is being used.
• Modify the CMakeLists.txt to include a direct call to the project() command as suggested by the CMake warning.
