Ошибка CMake при попытке добавить библиотеки opencv

Question

Я пытаюсь работать с датчиком глубины и пытаться получить изображение в градациях серого и отображать его с помощью OpenCV. Я могу получить доступ к данным с датчика глубины без каких-либо проблем. Но я получаю следующие ошибки при попытке включить OpenCV участия в CMakeLists.txt:

CMake Error at /usr/share/cmake/Modules/FindPackageHandleStandardArgs.cmake:148 (message): 
    Could NOT find CUDA (missing: CUDA_CUDART_LIBRARY) (found suitable exact 
    version "8.0") 
Call Stack (most recent call first):

Мой CMakeLists.txt выглядит следующим образом:

cmake_minimum_required(VERSION 2.8) 

set(CMAKE_PREFIX_PATH "share") 

find_package(royale REQUIRED) 

find_package(OpenCV REQUIRED) 

link_directories(${royale_LIB_DIR}) 

project (depthDataCallBack) 

include_directories(${CMAKE_CURRENT_SOURCE_DIR}/inc) 

add_executable(depthDataCallBack depthDataCallBack.cpp) 

target_link_libraries(depthDataCallBack "${royale_LIBS}") 

target_link_libraries(depthDataCallBack ${OpenCV_LIBS}) 

Я новичок в CMake. Поэтому всякая помощь будет оценена по достоинству. Благодаря!

Answer 1

project() звонок должен предшествующий вызов большинства других команд.

Как правило, только cmake_minimum_required() и назначения переменных могут быть получены до project().

Правильно:

cmake_minimum_required(VERSION 2.8) 

set(CMAKE_PREFIX_PATH "share") 

project (depthDataCallBack) 

find_package(royale REQUIRED) 
find_package(OpenCV REQUIRED) 
link_directories(${royale_LIB_DIR}) 

...
