Configure QT creator

Developed by QTProgramGenerally, you need to use qmake to generate the MAKEFILE file. Since qmake cannot identify spaces when parsing paths, it is necessary to ensure that the installation path of opencv cannot contain spaces (c: \ Program Files \ opencv is not acceptable ).

Add the following statement to the project when creating the project file (hello. Pro, Suffix: Pro:

Includepath + = D: \ QT \ OpenCV-2.0.0 \ include \ opencv

Libs + = D: \ QT \ OpenCV-2.0.0 \ Lib \ libcv200.dll. \
D: \ QT \ OpenCV-2.0.0 \ Lib \ libcxcore200.dll. \
D: \ QT \ OpenCV-2.0.0 \ Lib \ libml200.dll. \
D: \ QT \ OpenCV-2.0.0 \ Lib \ libcvaux200.dll. \
D: \ QT \ OpenCV-2.0.0 \ Lib \ libhighgui200.dll.

In this way, opencv 2.0 can be used in QT.
