Dear all,
Qt uses libjpeg to handle the JPG image format (compression and decompression). Does anyone know if it is possible to override the actual libjpeg used for linking in the qmake (.pro) file of a project?
Specifically, I would like to override usage of the standard libjpeg on my Debian system with an IPP (Intel Performance Primitives) version of libjpeg that resides in /opt/intel/ipp/6.0.2.076/em64t/lib/libjpeg.ipp.a and /opt/intel/ipp/6.0.2.076/em64t/sharedlib/libjpeg.ipp.so, since the IPP version is 2,5x as fast (which matters in my application).
Regards, Sidney
