Building with -DBUILD_SHARED_LIBS=ON is broken (again)

[fwyzard]

Building with -DBUILD_SHARED_LIBS=ON is broken (again) as of 0d56408 :

cmake \
  -DCMAKE_BUILD_TYPE=Release \
  -DLLVM_TARGETS_TO_BUILD="X86;NVPTX" \
  -DLLVM_EXTERNAL_PROJECTS="llvm-spirv;sycl;opencl-aot" \
  -DLLVM_ENABLE_PROJECTS="clang;llvm-spirv;sycl;opencl-aot;libclc" \
  -DLLVM_EXTERNAL_SYCL_SOURCE_DIR=$SYCL_BASE/llvm/sycl \
  -DLLVM_EXTERNAL_LLVM_SPIRV_SOURCE_DIR=$SYCL_BASE/llvm/llvm-spirv \
  -DBUILD_SHARED_LIBS=ON \
  -DLIBCLC_TARGETS_TO_BUILD="nvptx64--;nvptx64--nvidiacl" \
  -DSYCL_BUILD_PI_CUDA=ON \
  -DCUDA_TOOLKIT_ROOT_DIR=/usr/local/cuda \
  -DCUDA_USE_STATIC_CUDA_RUNTIME=OFF \
  $SYCL_BASE/llvm/llvm

make -j`nproc` sycl-toolchain

results in

I suspect the origin is #1306, given that the link failures are in LLVMSYCLLowerIR.

The full build log is attached.

Seems to be fixed by #1321.

Seems to be fixed by #1321.

Can we close this issue?

NOTE: we added this configuration to the post-commit, so hopefully we will detect commits regressing this configuration much earlier.

Fixed by #1321.
