Description

If I do not disable the ts library, I get the linking errors reported in attachment.
I am using MinGW 4.9.2 on X64 targeting 32bit
undefined reference to `cv::theRNG()
undefined reference to `cv::setNumThreads(int)'
undefined reference to `cvErrorStr'
undefined reference to `cvGetTickCount'
undefined reference to `cv::getTickFrequency()'
undefined reference to `cv::swap(cv::Mat&, cv::Mat&)'
undefined reference to `cv::matchTemplate(cv::_InputArray const&, cv::_InputArray const&, cv::_OutputArray const&, int)'
undefined reference to `cv::ocl::PlatformInfo::~PlatformInfo()'

Note:
- tbb is activated
- ipp is deactivated (See comments here http://answers.opencv.org/question/40159/cannot-compile-opencv-30/)

To be more precise: library ts can be created, what trigger the linking error is activating BUILD_TESTS/BUILD_PERF_TESTS (Which are disabled if the ts library is not built).

It's an error in the order in which the library are listed in the command line. See the 2 version below. The first is the repository one and fails, the second works, by placing linking to opencv_ts library before the other opencv libraries.
