For example: -DCMAKE_PREFIX_PATH:STRING=/home/jchris/Qt5.0.2/5.0.2/gcc_64/ Finally, this commit also resolves the build errors reported below. Fix missing header build error by including Qt headers directly without specifying the intermediate directory. * Fix build error changing QString::toAscii into QString::toLatin The method "toAscii" has been deprecated and is not available in default Qt5 distribution.
