Why libMLIRMemRef cannot be found after installing MLIR

Beginners

My configuration is as follows：
cmake -G Ninja …/llvm
-DLLVM_ENABLE_PROJECTS=mlir
-DLLVM_BUILD_EXAMPLES=OFF
-DLLVM_TARGETS_TO_BUILD=X86
-DCMAKE_BUILD_TYPE=Debug
-DLLVM_ENABLE_ASSERTIONS=ON
-DCMAKE_C_COMPILER=clang
-DCMAKE_CXX_COMPILER=clang++
-DLLVM_ENABLE_LLD=ON
-DLLVM_CCACHE_BUILD=ON
-DLLVM_INSTALL_UTILS=ON
-DMLIR_INCLUDE_INTEGRATION_TESTS=ON

cmake --build . --target check-mlir mlir-tblgen

You ran the test-suite and built the tblgen tool. You did not install anything.

ninja install-mlir-libraries

Or more minimalistic:

ninja install-MLIRMemRefDialect

Thank you, my problem has been resolved.
