[Compile] lcms(1) and libxml2 in ImageMagick

[henrywho]

I have two questions compiling ImagMagick 6.

[1] I have both lcms1 and lcms2 compiled and installed under MinGW x64. ImageMagick's configure found both but ended up using lcms2 only (-llcms2 but no -llcms). Is it how the config is meant to be?

[2] What is the use of libxml2? ImageMagick seems to be able to read the XML config files even if I did not compile in libxml2.
