CMake Error when trying to build for specific gpu arch

[mamei16]

System Info

OS: openSUSE Leap 15.6 ROCm version: 6.2.0 GPU: AMD Radeon RX 6800M CMake version: 3.28.3

Reproduction

git clone --recurse https://github.com/ROCm/bitsandbytes
cd bitsandbytes
git checkout rocm_enabled
pip install -r requirements-dev.txt
export CXX=/opt/rocm/llvm/bin/clang++
export CC=/opt/rocm/llvm/bin/clang
export Clang_DIR=/opt/rocm/llvm/lib/cmake/clang
export LLVM_DIR=/opt/rocm/llvm/lib/cmake/llvm
export AMDDeviceLibs_DIR=/opt/rocm-6.2.0/lib/cmake/AMDDeviceLibs/
export amd_comgr_DIR=/opt/rocm-6.2.0/lib/cmake/amd_comgr/
cmake -DCOMPUTE_BACKEND=hip -DAMDGPU_TARGETS=gfx1030 -S .

Expected behavior

No error should occur.

It seems simply moving the enable_language(HIP) line down to line 198 below the if statements fixes the issue.
