find_package allows to specify optional components. This way, the command will not fail if any of the components marked as optional was not found. This is useful in cases where components such as xfeatures2d, viz etc. are not available either because they were not compiled by the user or package maintainers decided to not provide the packages at all. The user can check the availability of the optional component using the OpenCV_<component>_FOUND variable.

# The OpenCV CMake configuration file

# ** File generated automatically, do not modify **

# Usage from an external project:
|
|
# In your CMakeLists.txt, add these lines:
|
|
#
|
|
# find_package(OpenCV REQUIRED)
|
|
# include_directories(${OpenCV_INCLUDE_DIRS}) # Not needed for CMake >= 2.8.11
|
|
# target_link_libraries(MY_TARGET_NAME ${OpenCV_LIBS})
|
|
#
|
|
# Or you can search for specific OpenCV modules:
|
|
#
|
|
# find_package(OpenCV REQUIRED core videoio)
|
|
#
|
|
# You can also mark OpenCV components as optional:
|
|
|
|
# find_package(OpenCV REQUIRED core OPTIONAL_COMPONENTS viz)
|
|
#
|
|
# If the module is found then OPENCV_<MODULE>_FOUND is set to TRUE.
|
|
#
|
|
# This file will define the following variables:
|
|
# - OpenCV_LIBS : The list of all imported targets for OpenCV modules.
|

# - OpenCV_INCLUDE_DIRS : The OpenCV include directories.
|
|
# - OpenCV_COMPUTE_CAPABILITIES : The version of compute capability.
