    <p>I am trying to write a C++ application using the OpenCV libraries. As per the recommendation from the OpenCV maintainers, I am using CMake to generate the Makefile. My platform is Windows 7 (64 bit). My compiler is MinGW (so I am using the 'mingw32-make' tool to build the application).</p> <p>Right now I am trying to make sure my setup is correct so I can move forward with the code. I have verified that the OpenCV libraries have been built correctly. I then tried to verify that I could use CMake to include the OpenCV libraries in my build. I am using the following sample code from an OpenCV tutorial:</p> <p>DisplayImage.cpp</p> <pre><code>#include &lt;cv.h&gt; #include &lt;highgui.h&gt; using namespace cv; int main( int argc, char** argv ) { Mat image; image = imread( argv[1], 1 ); if (argc != 2 || !image.data) { printf( "No image data \n" ); return -1; } namedWindow( "Display Image", CV_WINDOW_AUTOSIZE ); imshow( "Display Image", image ); waitKey(0); return 0; } </code></pre> <p>CMakeLists.txt</p> <pre><code>cmake_minimum_required( VERSION 2.8 ) project( DisplayImage ) find_package( OpenCV REQUIRED ) add_executable( DisplayImage DisplayImage ) target_link_libraries( DisplayImage ${OpenCV_LIBS} ) </code></pre> <p>I used cmake-gui to generate the Makefile, then used mingw32-make to build the application. Everything works fine and the program compiles with no errors. However, when I try to run it, Windows stops and complains that it needs libopencv_core231.dll. I have checked and this dll is in my (OpenCV Build location)/bin directory. How can I get CMake/MinGW to include this when compiling?</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
