Where in the llvm/clang CMake files is libxml specified ?<span class=""><br>

Maybe CMake finds your libxml2 but does not check if its 32 or 64 bit,<br>
just assumes it's the right one?<br>

I queried this on the CMake mailing list and am awaiting some answer from them. But I expect that if I get one it will be to ask where llvm/clang specifies libxml in its CMakeLists.txt files.<br>

No, I am not. Ninja is calling mingw-64/gcc-5.3 directly to build<br>
llvm/clang<br>
<br>
.<br>

<br>
I do have a 32-bit libxml2 on my Windows PATH from the GnuWin32<br>
package.<br>
But why is a build of llvm/clang requiring libxml2, whether a<br>
32-bit or<br>
64-bit version ?<br>
<br>
<br>
I don't know why CMake finds but doesn't ignore it.<br>
c-index-test uses libxml2 if available. libxml2 is not essential.<br>
<br>
We could add extra checks if libxml2 would be really available.<br>

<br>
Why would using gcc-4.9.3 make any difference ?<br>
<br>
<br>
Excuse me. It was just an example. Please substitute with your<br>
mingw-w64's path.<br>
