Error when compiling with the lastest OpenCV trunk version [SOLVED]

I am using the latest trunk version of OpenCV ( opencv 2.4.0 ).

But when configuring the trunk version of MRPT, CMake automatically detected a version of 2.3.3, which causes some compiling errors.

I found no options in CMake to set a correct version of opencv. So how can I get it work?

Thanks a lot.

I found the OPENCV_IGNORE_PKGCONFIG option.

It works fine now.
