<div>
<pre>When trying to build trunk with flang included, I initially used
cmake -DLLVM_ENABLE_PROJECTS="clang;clang-tools-extra;compiler-rt;polly;flang"
...
Unfortunately, this failed rather obscurely with
CMake Error at
/vol/llvm/src/llvm-project/dist/flang/include/flang/Optimizer/Dialect/CMakeLists.txt:5
(mlir_tablegen):
Unknown CMake command "mlir_tablegen".
I'd have expected either that flang adds the required dependency on mlir
automatically
or at the very least clearly diagnoses early on that it's missing.</pre>
