[I] [Bug] CMake minimum version too low [tvm]

["varunsh-xilinx (via GitHub)" <gi...@apache.org>]

varunsh-xilinx opened a new issue, #16233:
URL: https://github.com/apache/tvm/issues/16233

   The CMake version in `CMakeLists.txt` [here](https://github.com/apache/tvm/blob/main/CMakeLists.txt#L1) is too low at 3.18. New changes require at least 3.20.0:
   
   * In `ubuntu_install_cmake_source.sh`, the [default version is set](https://github.com/apache/tvm/blob/main/docker/install/ubuntu_install_cmake_source.sh#L23-L28) to 3.20.0 with a note that LLVM 16+ requires it.
   * #16081 adds `cmake_path` to `cmake/utils/FindLLVM.cmake`. This [command ](https://cmake.org/cmake/help/latest/command/cmake_path.html)exists in CMake 3.20+.
   
   ### Expected behavior
   
   If the CMake version is unsupported, it should fail at `cmake_minimum_required()`.
   
   ### Actual behavior
   
   The build failed in `FindLLVM.cmake` when `cmake_path` couldn't be found as a CMake command:
   ```
   CMake Error at cmake/utils/FindLLVM.cmake:121 (cmake_path):
     Unknown CMake command "cmake_path".
   Call Stack (most recent call first):
     cmake/modules/LLVM.cmake:31 (find_llvm)
     CMakeLists.txt:528 (include)
   ```
   
   ### Environment
   
   Tried on a custom Ubuntu 20.04 container with TVM commit a9fcac1a47f4b57c1d9d828c7ed1d77452b02cc5.
   
   ### Steps to reproduce
   
   Attempt to build TVM with CMake 3.19.1.
