Did you also run the tests? This is where i struggle atm. Tests seem
to fail in a good amount and finally hang.
Which tests fail? Are you building with make or ninja? I'm of the mind
to use ninja for all cmake based packages (at least where possible,
there was a limitation, a corner case, but I don't recall what it was).
I do not build the docs, but if they are desired, then I think they
probably have to be included in the first cmake command line with ninja
adding -DLLVM_BUILD_DOCS=ON and the two sphinx defines already in the book.
I'm using the following:
{{{
CC=gcc CXX=g++ \
cmake -DCMAKE_INSTALL_PREFIX=/usr \
-DLLVM_ENABLE_FFI=ON \
-DCMAKE_BUILD_TYPE=Release \
-DLLVM_BUILD_LLVM_DYLIB=ON \
-DLLVM_LINK_LLVM_DYLIB=ON \
-DLLVM_TARGETS_TO_BUILD="host;AMDGPU" \
-DLLVM_BUILD_TESTS=ON \
-Wno -G Ninja .. &&
ninja -j12
ninja check{,-clang{,-tooling}} 2>&1 | tee clang-check-log.txt
ninja install
}}}

I limit all ninja builds, as a matter of course, to 12 threads as I get
OOMs with only 16GB of RAM on Chromium (but seems it was OK for tests,
as I forgot about it above). Also of note is that I am on multi-lib from
lfs-systemd-20180803, so 'host' builds both x86_64 and i386. Finally, I
build in chroot until Xorg (so building as root for the moment).
