However, the websockets client is based on Websockets++, which adds mandatory dependencies on boost, openssl, and zlib. To implement the HTTP client functionality on Windows Desktop, only the core Win32 platform APIs are needed ( zlib is optional). The C++ REST SDK is a networking library that provides (among other features) HTTP and Websockets clients.
Open cv for windows or mac install#
For maintainers, there must be a way to specify this requirement such that vcpkg install mylib-depends-ocv-contrib will verify/build/rebuild OpenCV with the community extensions enabled. It would be convenient, but not a requirement, to enable CUDA without enabling the community extensions.įinally, these extensions add additional exports and headers which could be depended upon by other libraries. Likewise, when a user requests OpenCV_contrib, CUDA must be enabled. Therefore, if CUDA is disabled, OpenCV_contrib must also be disabled.
Further confounding the problem, it is the author's understanding that these community extensions have only been developed with CUDA enabled and cannot be built without that dependency.
Open cv for windows or mac Patch#
However, these extensions are a source-level patch onto the main OpenCV codebase and therefore must be applied during the core OpenCV build. The community around OpenCV has built up a library of extensions called OpenCV_contrib. Therefore, there is significant value in enabling users to choose whether they find CUDA support valuable for their particular scenario. CUDA is provided only via a 1.3 GB installer (at the time of this authoring), which requires administrator access to install and modifies the global system state. For users without NVidia GPUs, building with CUDA support provides no benefit. OpenCV is a computer vision library that can optionally be built with CUDA support to massively accelerate certain tasks when using computers with NVidia GPUs. Up-to-date documentation is available at Selecting Library Features. Note: this is the feature as it was initially specified and does not necessarily reflect the current behavior.
