# Standalone OpenCV plugins build scripts |

# Useful OpenCV common build variables: |
|
# - CMAKE_BUILD_TYPE=Release/Debug |
|
# - BUILD_WITH_DEBUG_INFO=ON |
|
# - ENABLE_BUILD_HARDENING=ON |
|

|
# Plugin configuration variables: |
|
# - OPENCV_PLUGIN_DEPS - set of extra dependencies (modules), used for include dirs, target_link_libraries |
|
# - OPENCV_PLUGIN_SUFFIX |
|
# - OPENCV_PLUGIN_NAME |
