#249 WARNING: you are using the obsolete 'PKGCONFIG' macro, use F

[Mathieu Malaterre]

I cannot properly compile code from: https://github.com/Nakull/GDCM

it reports:

-- WARNING: you are using the obsolete 'PKGCONFIG' macro, use FindPkgConfig
-- Found LibXml++: /usr/lib/libxml++-2.6.so

Thanks !

Will do the following changes.
Was still working on it. There were some other issues as well while integrating libxml++.
It had dependencies on glib packages which were causing trouble.
