So in most cases, include opencv.hpp may be enough if you do not care about compilation time (see also here and here for more discussions on this).
Opencv build cmake linux install#
I think you want INTERFACE_LINK_LIBRARIES instead here. Install minimal prerequisites (Ubuntu 18.04 as reference) sudo apt update & sudo apt install -y cmake g++ wget unzip. If you look at the header file opencv.hpp, you will find that it actually includes other OpenCV header files, if they are not included in your code already.

Which puzzles me is that in both cases (with or without OpenCV::OpenCV wrapping) all environment and cmake variables are the same… With CMake 3.19 works so it seems to be really an issue with the way I create OpenCV::OpenCV Set_target_properties(OpenCV::OpenCV PROPERTIES I require all my dependencies to use namespace for homogeneity but OpenCV does not provide OpenCV::OpenCV.Īdd_library(OpenCV::OpenCV UNKNOWN IMPORTED)
I’ve got an application A that depends privately on L and OpenCVįind_package(OpenCV REQUIRED) finds the 3.3 version, which is what I expect. I’ve got a static library L that depends publicly on OpenCV I fail to properly add a dependency to opencv3 in my devs.Ģ.4 which is the default one for ubuntu 16.04
