llvm dev - Dec 2015 - LLVM fails to install with ocaml enabled

Hi,

I'm playing around with LLVM and stumbled upon this issue while while 
performing "make install". The build itself was successful. I'm
using
the latest git version.

#make install

-- Installing: /home/alesko/llvm-install/bin/llvm-mc
-- Installing: /home/alesko/llvm-install/bin/sancov
-- Installing: /home/alesko/llvm-install/bin/opt
-- Installing: /home/alesko/llvm-install/bin/llvm-split
-- Installing: /home/alesko/llvm-install/bin/llvm-cov
-- Installing: /home/alesko/llvm-install/bin/obj2yaml
CMake Error at docs/cmake_install.cmake:36 (file):
   file INSTALL cannot find
   "/home/alesko/repositories/build-llvm/docs/ocamldoc/html".
Call Stack (most recent call first):
   cmake_install.cmake:66 (include)



Makefile:93: recipe for target 'install' failed
make: *** [install] Error 1


Without ocaml, install works fine.

What am I missing?

regards,
Alen

Not sure, but my guess is that the ocaml documents targets aren’t being included
in the ALL target, which is resulting in them not being built before the install
action.

The fix for this will probably involve changing the add_custom_target command at
docs/CMakeLists.txt:146 to be split out into several add_custom_command calls
that have output files, and making the target depend on the output files.

I think you're right. Running "make ocaml_doc" then rerunning
"make install" completed the build.

Adding "ALL" to that add_custom_command let a general "make
&& make install" build finish. Is that a viable fix, or would it
have some other effects I'm not aware of?
