Question

我正在尝试使用深度传感器并尝试获取灰度图像并使用OpenCV显示它。我可以毫无问题地从深度传感器访问数据。但是当我尝试在CMakeLists.txt中包含OpenCV部分时，我收到以下错误：

我的CMakeLists.txt如下所示：

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})

我是CMake的新手。所以任何和所有的帮助将不胜感激。谢谢！

project()调用在之前调用大多数其他命令。

通常情况下，只有cmake_minimum_required()和变量分配可能会出现在project()之前。

正确：

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})

...
