To enable testing (and automatic result upload to http://my.cdash.org/index.php?project=OPENJPEG) : svn co http://openjpeg.googlecode.com/svn/trunk openjpeg-read-only cd openjpeg-read-only cmake -G "Unix Makefiles" -DBUILD_TESTING:BOOL=ON -DJPEG2000_CONFORMANCE_DATA_ROOT:PATH=/path/to/your/JPEG2000/test/files make Experimental Note : JPEG2000 test files are available here : http://www.crc.ricoh.com/~gormish/jpeg2000conformance/
