[Shell script below]<br>
<br>
I then built LLVM using CMAKE and without OCAML.<br>
<br>
My version of cmake is 3.3.1. I did built it myself.<br>
<br>
I get the following. Thought the list should know.<br>

CMake Warning (dev) at cmake/modules/AddLLVM.cmake:5 (get_property):<br>
Policy CMP0051 is not set: List TARGET_OBJECTS in SOURCES target property.<br>
Run "cmake --help-policy CMP0051" for policy details. Use the cmake_policy<br>
command to set the policy and suppress this warning.<br>
<br>
Target "clang-tblgen" contains $<TARGET_OBJECTS> generator expression in<br>
its sources list. This content was not previously part of the SOURCES<br>
property when that property was read at configure time. Code reading that<br>
property needs to be adapted to ignore the generator expression using the<br>
string(GENEX_STRIP) command.<br>
Call Stack (most recent call first):<br>
cmake/modules/AddLLVM.cmake:600 (llvm_update_compile_flags)<br>

cmake/modules/TableGen.cmake:82 (add_llvm_utility)<br>
tools/clang/utils/TableGen/CMakeLists.txt:3 (add_tablegen)<br>
This warning is for project developers. Use -Wno-dev to suppress it.<br>
