libclc CMake error: unknown arguments specified

[hwnam831]

I cannot build libclc in both llvm-13 and llvm-15 due to the following error:

`LLVM version:
CMake Error at /home/hwnam/llvm-project/libclc/CMakeLists.txt:51 (if):
if given arguments:

"VERSION_LESS" "3.9.0"

Unknown arguments specified`

It seems like the following function does not set the environmental variable $LLVM_VERSION correctly.
`execute_process( COMMAND ${LLVM_CONFIG} "--version"
OUTPUT_VARIABLE LLVM_VERSION
OUTPUT_STRIP_TRAILING_WHITESPACE )
message( "LLVM version: ${LLVM_VERSION}" )

if( ${LLVM_VERSION} VERSION_LESS ${LIBCLC_MIN_LLVM} )
message( FATAL_ERROR "libclc needs at least LLVM ${LIBCLC_MIN_LLVM}" )
endif()`

Is there any additional argument/environment I need to build libclc?

The aforementioned parts of libclc/CMakeLists.txt no longer seems to exist.

With LLVM @ recent main commit 8663b8777e8108f74f91a2a33115b3a00d57c043,
I don't see any CMake errors when building libclc from source.
