junrushao1994 opened a new issue #16245: [Build][CMake] LIBOMP: Cannot find llvm-lit
URL: https://github.com/apache/incubator-mxnet/issues/16245
## Description
Hey, I am trying building MXNet from source using CMake. Although I am able to build it, cmake does produce some warnings that I would love to configure out why.
```
-- LIBOMP: Cannot find llvm-lit.
-- LIBOMP: Please put llvm-lit in your PATH, set LIBOMP_LLVM_LIT_EXECUTABLE to its full path or point OPENMP_LLVM_TOOLS_DIR to its directory
CMake Warning at 3rdparty/openmp/runtime/cmake/LibompUtils.cmake:21 (message):
LIBOMP: The check-libomp target will not be available!
Call Stack (most recent call first):
3rdparty/openmp/runtime/test/CMakeLists.txt:62 (libomp_warning_say)
```
I suppose that openmp is downloaded by the cmake script and built from scratch, so shouldn't it be self-contained? So is there any flags that i missed out? Any ideas would be super helpful!
