Book Learning OpenCV 3- Computer Vision in C++ With the OpenCV Library by Adrian Kaehler and Gary Bradski reads:
Installing on Windows. At the page: Releases - OpenCV , you will see a link to download the latest version of OpenCV for Windows. This link will download an executable file which you can run, and which will install OpenCV, register DirectShow filters, and perform various post-installation procedures.
You are now almost ready to start using OpenCV. The one additional detail is that you will want to add is an OPENCV_DIR environment variable to make it easier to tell your compiler where to find the OpenCV binaries. You can set this by going to a command prompt and typing
setx -m OPENCV_DIR D:\OpenCV\Build\x86\vc10
If you built the library to link statically, this is all you will need.
If you built the library to link dynamically, then you will also need to tell your system where to find the library binary.
====end of quote
My static linking fails to find libs (OpenCV-4). Google advice: Pre-built binaries are now shared (DLL) only. Static linking requires building from source
Is this the case?
