pip install from source broken with link failure on x86_64-linux-gnu-centos-7-release

[david-vc]

The installer downloaded llvm+mlir-17.0.0-x86_64-linux-gnu-centos-7-release; I'm compiling with gcc10.
I'm getting this link error in the step that builds unittest/Dialect/TritonGPU/TestSwizzling:

Combine.cpp:211: undefined reference to mlir::FrozenRewritePatternSet::FrozenRewritePatternSet(mlir::RewritePatternSet&&, llvm::ArrayRef<std::__cxx11::basic_string<char, std::char_traits, std::allocator > >, llvm::ArrayRef<std::__cxx11::basic_string<char, std::char_traits, std::allocator > >)

Looking at llvm+mlir-17.0.0-x86_64-linux-gnu-centos-7-release/include/mlir/Rewrite/FrozenRewritePatternSet.h, I do not see this constructor variant with 2 array refs.

Also:

Notice the difference in signatures.: llvm::ArrayRef<std::__cxx11::basic_string<char, std::char_traits, std::allocator > > vs llvm::ArrayRef<std::string >
I'd appreciate suggestions.

After installing gxx, libgcc, pytorch-gpu in a conda, I was able to build triton from source as per instructions. Sorry for the noise.
