Question

我正在尝试使用cmake来编译OpenCV 3.0中的代码。我试着让它变得尽可能简单：

project(xxxxx)
cmake_minimum_required(VERSION 2.8)
aux_source_directory(. SRC_LIST)
find_package(OpenCV)
message("Libs: ${OpenCV_LIBS}")
message("Include Dir: ${OpenCV_INCLUDE_DIRS}")
include_directories(${OpenCV_INCLUDE_DIRS})
add_executable(${PROJECT_NAME} ${SRC_LIST})
target_link_libraries(${PROJECT_NAME}
${OpenCV_LIBS}
)

我在main.cpp中的所有内容都是：

#include <opencv2/core.hpp>

和

cv::UMat trqw;

我得到了＃34;没有规则来制定目标＆＃34;错误。该错误表明它正在查看＆＃34; opencv-3.0.0 / lib /＆＃34;文件夹不存在，它应该在＆＃34; opencv-3.0.0 / build / lib /＆＃34;中查找。当我构建OpenCV使CMAKE包看起来错误时，我做错了什么，如果没有，我的CMakeLists.txt是否有更好的方法来指导它查找正确的文件夹？我试过＆＃34; $ {OPENCL_LIBRARIES}＆＃34;在target_link_libraries调用中没有变化。

谢谢！

----编辑----------------

是的，我的cmakelists.txt中确实有find_package（OpenCV），谢谢！我也试过find_package（OpenCV 3.0）和find_package（OpenCV 3.0 REQUIRED）但没有用。

----------编辑--------------- 输出

message("Libs: ${OpenCV_LIBS}") # I added it to the orig question

感谢Tsyvarez提供的所有帮助！

def sortable(column, title = nil)
  title ||= column.titleize
  d = (column == sort_column && sort_direction == 'asc') ? 'desc' : 'asc'
  link_to (title + glyph("sort-#{sort_direction}") ).html_safe, sort: column, direction: d

前

set ( OpenCV_DIR   "/home/xxxxx/opencv-3.0.0/build/")

在cmakelists.txt

中

谢谢！

如何解决：-1：错误：没有规则来制作目标`/home/xxxxx/opencv-3.0.0/lib/libopencv_xphoto.so.3.0.0&#39 ;,需要`xxxxx＆＃39;。停止
