Since CMake can't successfully locate OpenJPEG [1], it is falling back
to "JPXStream.cc", i.e. line 445 in "CMakeLists.txt".

And here I find that "JPEG2000Stream.h" instead of "JPXStream.cc" is
incorrectly included for example into "Stream.cc".

I think this is due to "ENABLE_LIBOPENJPEG" being defined in "config.h"
which would indicate that "LIBOPENJPEG_FOUND" is actually true even
though the headers cound not be found? But from looking at the CMake
modules I do not understand this ATM as well...

Best regards, Adam.
