<br>
This means that OpenCV's *Targets.cmake file is not read.  This file<br>
informs CMake of all the imported library targets' full paths.<br>
<br>
To ensure this file is read, 'find_package(OpenCV)' should be called.<br>
This reads in the OpenCVConfig.cmake file, which should read in the<br>
OpenCVTargets.cmake file (I have not checked if these files have these<br>
exact names, but that is the idea).<br>
<br>
To make this happen,<br>
<br>
  Modules/Video/BridgeOpenCV/CMakeLists.txt<br>
<br>
should set ITKVideoBridgeOpenCV_EXPORT_CODE_BUILD and<br>
ITKVideoBridgeOpen_EXPORT_CODE_INSTALL to strings that contain<br>
<br>
  set(OpenCV_DIR \"${OpenCV_DIR}\")<br>
  find_package(OpenCV REQUIRED)<br>
<br>
The contents of these variable are added to a module's CMake<br>
information file, which is loaded when the module is loaded.<br>
<br>
The file<br>
<br>
  Modules/ThirdParty/DCMTK/CMakeLists.txt<br>
<br>
serves as a good example.<br>
