These errors seem pretty pervasive for me on a clean build. It appears that it arises because when tablegen'd headers are included in a .h file, every place where that .h file is used needs a dependency on the corresponding IncGen targets. This seems broken in the short term and unmaintainable in the long term. There really needs to be a way of automatically generating the right dependencies.

Not sure, tried couple of times. Seems like while building with "-DBUILD_SHARED_LIBS=ON" causes all these problems. However, building MLIR with this FLAG disabled -- building fine. --Sourabh.

Hello all,
FWIW, I am still hitting this [*] build error on release branch 10.x
(llvmorg-10.0.0-rc5) when building with:
`cmake -G Ninja
-DLLVM_ENABLE_PROJECTS="clang;compiler-rt;lld;polly;mlir"
-DCMAKE_INSTALL_PREFIX="/Users/johan/llvm/llvmtrunkinstall"
-DLLVM_TARGETS_TO_BUILD="AArch64;ARM;Mips;MSP430;NVPTX;PowerPC;X86"
-DLLVM_EXPERIMENTAL_TARGETS_TO_BUILD="RISCV;WebAssembly"
-DCMAKE_BUILD_TYPE=Release -DLLVM_ENABLE_ASSERTIONS=ON
-DLLVM_APPEND_VC_REV=ON -DLLVM_INSTALL_UTILS=ON ../../llvm` .
Note that I am building with Ninja, perhaps that's the reason?
Cheers,
Johan
