Compilation-installation issue related to documentation installation

Beginners
#1

I’m trying to compile a tag ‘llvmorg-14.0.5’ but I’m stuck with installation of compiled stuff. It says:

...
-- Up-to-date: /home/kakadu/mand/llvm/install/include/clang-c/CXString.h
-- Up-to-date: /home/kakadu/mand/llvm/install/include/clang-c/CXErrorCode.h
CMake Error at tools/clang/docs/cmake_install.cmake:46 (file):
  file INSTALL cannot find
  "/home/kakadu/mand/llvm/build/tools/clang/docs/doxygen/html": No such file
  or directory.
Call Stack (most recent call first):
  tools/clang/cmake_install.cmake:71 (include)
  tools/cmake_install.cmake:53 (include)
  cmake_install.cmake:78 (include)

I install using cmake --build . -j4 --target install and my configuration command looks like

cmake -G Ninja -DCMAKE_BUILD_TYPE=Debug \
 -DBUILD_SHARED_LIBS=Dynamic -DLLVM_ENABLE_PROJECTS='clang'  \
 -DLLVM_TARGETS_TO_BUILD="X86" -DLLVM_EXPERIMENTAL_TARGETS_TO_BUILD=RISCV  \
 -DLLVM_USE_SPLIT_DWARF=ON ../llvm-project/llvm  \
 -DCMAKE_INSTALL_PREFIX=~/mand/llvm/install -DLLVM_ENABLE_DOXYGEN=ON \

I’m not sure is it a peculiarity of LLVM or my cmake-fu requires level-up. Any ideas?

#2

This issue happens not on every machine, so I still don’t know why it happens.
But it looks like creating a required directory by hand is a possible workaround.
