<pre>
    In the website [documentation](https://libc.llvm.org/full_host_build.html) for building libc, this command is given to configure it properly.

```
cmake ../llvm  \
   -G Ninja  \ # Generator
 -DLLVM_ENABLE_PROJECTS="clang;libc;lld;compiler-rt"   \ # Enabled projects
   -DCMAKE_BUILD_TYPE=<Debug|Release>  \ # Select build type
 -DCMAKE_C_COMPILER=clang -DCMAKE_CXX_COMPILER=clang++ \
 -DLLVM_LIBC_FULL_BUILD=ON      \  # We want the full libc
 -DLLVM_LIBC_INCLUDE_SCUDO=ON   \  # Include Scudo in the libc
 -DCOMPILER_RT_BUILD_SCUDO_STANDALONE_WITH_LLVM_LIBC=ON \
 -DCOMPILER_RT_BUILD_GWP_ASAN=OFF                       \
 -DCOMPILER_RT_SCUDO_STANDALONE_BUILD_SHARED=OFF        \
 -DCMAKE_INSTALL_PREFIX=<SYSROOT>  # Specify a sysroot directory
```

However, upon doing this, apparently one of the options is not used, is this deprecated or new and not fleshed out? Or just not supposed to be there?
```
CMake Warning:
  Manually-specified variables were not used by the project:

 LLVM_LIBC_INCLUDE_SCUDO
```
