[build] Fix CMake for CAPI

[lschuetze]

While importing and using linalg dialect Python bindings the following error occured:

ImportError: dlopen(/Users/lschuetze/git/hybrid-quantum/build/python_packages/quantum-mlir/mlir/_mlir_libs/_mlirDialectsLinalg.cpython-313-darwin.so, 0x0002): symbol not found in flat namespace '_mlirLinalgFillBuiltinNamedOpRegion'

CMake for the CAPI has to be checked to find the root cause. This bug can be used to track further bugs in the build system configuration. By now we can ignore the bug since we do not require linalg dialect in the Python bindings.
