The instructions on:

We can now run CMake:

-DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=/usr
<libc++-source-dir>
however, it does not say what to put for <libc++-source-dir>
or in which directory this command is to be run. One might
guess this command is to be run inb the directory where the buildit
script is located, because that's what the earlier instructions
(for Mac OS) were run from; however, that's not at all clear.
CMake encourages out of source build.
You run CMake in your build directory and you point it to your source
diectory (the one with CMakeLists.txt).
E.g.:
/libcxx_build
/libcxx
/include
CMakeLists.txt
cd /libcxx/build
CMake ../libcxx
Or:
/libcxx
/build
/include
CMakeLists.txt
cd /libcxx/build
CMake ..

Thanks Ben.
I tried the 2nd directory hierarchy:

Then tried the Cmake command; however, it failed because some
function body was unavailable for inlining, as shown by:
