OpenCV, Eigen and FlyCapture libraries not detected by VIPS on Windows10

[Ivan-Jordan96]

I have installed VISP from source for Windows 10 with Visual C++ 2019 (vc16). And I have installed also OpenCV, Eigen, and FlyCapture as 3rd parties, following all the steps of the website.

1. I can see OpenCV and Eigen as 3dr parties in the ViSP-third-party.txt file, but not FlyCapture,
2. When I tried to run some Examples from VISP, OpenCV and Eigen are not detected.
   Thanks for your help!
   Best regards.

From what I see, you have a build error with Eigen. I suspect that you don't follow carefully all the steps to install Eigen (see tutorial), especially the command to install Eigen

cmake --build . --config Release --target install

Concerning Flycapture, did you carefully follow the tutorial and complete Flycapture SDK installation by adding C:\Program Files\Point Grey Research\FlyCapture2\bin64 to the Path environment var ?

Don't forget that after modifying the Pathenv var, you need to quit cmake-gui and all cmd windows, before opening them again so that the env vars are taken into account.

Thank you for your quick response.
I will try to reinstall VISP and the different third parties.
Please, is it mandatory to install Flycapture SDK in C:\Program Files?
Best Regards.

You can install Flycapture SDK where you want, but you have then:

• to add the location of the DLL in the Path var
• add a new var named FLYCAPTURE_HOME that points to your other installation location (see here)
• I suspect that you will also have to modiy this line and this line, by using rather list(APPEND FLYCAPTURE_INC_SEARCH_PATH "$ENV{FLYCAPTURE_HOME}/include")

Let me know, so that I can commit the changes in the code.

Thank you again for these methods, everything works now even FlyCapture. But VIPS doesn't detect my camera and I will try to solve that. In this image, you can see what I got when I run tutorial-grabber-flycapture.
Best regards.

I want to specify that I used a BlackFly color camera S UBS 3.1 BFS-U3-63S4C-C.
