Funny you should mention this... because I spent half of yesterday debugging a problem which turned out to be related to openjpeg.  I use ITK 3.20 and GDCM 2.2.3, and point ITK to my GDCM.   I then link my app against ITK and GDCM.  At runtime, I was getting crashes with JPEG2000 DICOM files, I thought it was a GDCM bug:

<https://sourceforge.net/p/gdcm/bugs/220/>

But turned out that I was linking to both ITK's and GDCM's openjpeg.  If ITK's was linked to first, I'd crash; if GDCM's was first, I wouldn't.

Cheers,
