I am installing llvm in a clean build and I got a linker error when building it.
I have configured it with the following options.
~~~
cmake -S llvm -B build -G "Unix Makefiles" -DLLVM_ENABLE_PROJECTS="clang;clang-tools-extra;compiler-rt;polly" -DCMAKE_BUILD_TYPE=Release
~~~
And then when building it executing `cmake --build build` the following error appears.
