lib/libMLIRLLVMIRTransforms.a fails to build from scratch with the following error:
In file included from llvm/include/llvm/Frontend/OpenMP/OMPConstants.h:19,
from llvm/include/llvm/Frontend/OpenMP/OMPIRBuilder.h:19,
from mlir/include/mlir/Target/LLVMIR/ModuleTranslation.h:26,
from mlir/include/mlir/Dialect/LLVMIR/NVVMDialect.h:24,
from mlir/lib/Dialect/LLVMIR/Transforms/InlinerInterfaceImpl.cpp:17:
llvm/include/llvm/Frontend/OpenMP/OMP.h:16:10:
fatal error: llvm/Frontend/OpenMP/OMP.h.inc: No such file or directory
I believe this issue has been exposed by 8d306ccdef6b70881f5d79b09c03df720351e5f8 (@wsmoses ) which added an include of mlir/Dialect/LLVMIR/NVVMDialect.h
in mlir/lib/Dialect/LLVMIR/Transforms/InlinerInterfaceImpl.cpp
I tried adding a dependency on MLIRTargetLLVMIRExport but it then causes a dependency cycle due to MLIRTargetLLVMIRExport linking against MLIRLLVMIRTransforms. This cycle does not exist in the bazel build despite NVVMDialect linking against ToLLVMIRTranslation because ToLLVMIRTranslation depends on LLVMIRTransformsLegalizeForExport instead of the whole LLVMIRTransforms. Perhaps a similar approach can be taken in CMake? Any thought @Dinistro ?
