I'm using make, and "make -C /my/build/dir mlir-tblgen" works for me.

Cmake-generated makefiles have target "help" that lists all available targets for make.  I don’t know about ninja.

I am building MLIR with LLVM, using the

LLVM_TOOL_MLIR_BUILD:BOOL=ON

option in CMakeCache. Indeed, the MLIR files are in my build tree.

Can someone tell me how to build just MLIR, or, better yet, just mlir-tblgen? I'm building llvm-tblgen with

ninja -j 6 bin/llvm-tblgen.exe

And so, silly me, I assumed I could just add

ninja -j 6 bin/mlir-tblgen.exe

But no joy. I haven't yet gotten the hang of specifying what to build.
