building in-tree from source error: Could not find FOUND_VCS #130

Looking into enabling opencl with SynoCommunity ffmpeg for x86_64 arch. Related PR: https://github.com/SynoCommunity/spksrc/pull/6148 (IGC, intel-clang-opencl and al not yet included in PR, pending this issue) Note: the following below without vc-intrinsics it does configure & build properly.

Building wiht vc-intrinsics in-tree from source with the following:

CMAKE_ARGS += -DLLVM_TARGETS_TO_BUILD=X86
CMAKE_ARGS += -DLLVM_ENABLE_PROJECTS='clang'
CMAKE_ARGS += -DLLVM_EXTERNAL_PROJECTS='llvm-spirv;opencl-clang;vc-intrinsics'
CMAKE_ARGS += -DLLVM_EXTERNAL_LLVM_SPIRV_SOURCE_DIR=$(WORK_DIR)/SPIRV-LLVM-Translator
CMAKE_ARGS += -DLLVM_EXTERNAL_SPIRV_HEADERS_SOURCE_DIR=$(WORK_DIR)/SPIRV-Headers
CMAKE_ARGS += -DLLVM_EXTERNAL_VC_INTRINSICS_SOURCE_DIR=$(WORK_DIR)/vc-intrinsics
CMAKE_ARGS += -DLLVM_EXTERNAL_OPENCL_CLANG_SOURCE_DIR=$(WORK_DIR)/$(PKG_NAME)

And getting the following configuration error (present with version 0.18.0, also tested much older 0.3.0, same issue):
