My problem not with compiling/installing ITK but when compiling libkml, a
dependency of OTB which uses ITK. This uses an expat library and instead of
using  a system expat i wind up using expat from ITK as expat.h is
installed in <prefix>/include/ITK4.6. I can confirm using system expat
doesnt have any problem with libkml when used with OTB.

If you would like to have a look at bug report, see here[1]. I had a
temporary solution to build libkml before adding itk headers but a best
would be to have a fix in ITK' expat library.

The issue is coming using an installed version of ITK.
So if you are planning to upgrade expat library to its latest version or
use system expat then the problem is solved.
