You could try to force libxml to be ignored by CMake so it will think it
wasn't found and use the fallback configuration:
cmake ... -DLIBXML2_LIBRARIES=IGNORE ...
I will try that, thanks !
But shouldn't CMake be able to distinguish between a 32-bit and a 64-bit
version of a library when 'find_package(some_library)' is specified ?

Building llvm/clang from source involves using CMake. I am building
llvm/clang from source on Windows using CMake 3.5.2. I am not a
clang developer, just a clang user. Similarly I just use CMake
rather than understand or write CMakeLists.txt files.
I reported a problem to clang where building a 32-bit version of
clang succeeds but building a 64-bit version of clang fails with xml
link errors. I have A 32-bit libxml2 binary in my path from
gnuwin32, but not a 64-bit binary of libxml2 in my path.
I was told by clang developers that one of the tools which clang
builds uses xml and libxml2 if it is available, otherwise uses some
other technology for the tool. The suggestion was that the problem I
am encountering is that of CMake; that CMake does not recognize that
the libxml2 which I have is the 32-bit version and instead thinks
that it is the 64-bit version and therefore attempts erroneously to
use it in the 64-bit build of clang.
Does anybody know what might be happening here ? I do not create the
CMakeLists.txt files used by llvm/clang so I do not know how the use
of libxml2 can be optionally specified in them.
