我下载了zbar库，并将opencv-zbar存储库克隆到我的主目录中。然后我运行了以下命令$cmake .，给了我错误
-- Could NOT find ZBAR (missing: ZBAR_LIBRARIES ZBAR_INCLUDE_DIR) CMake Error: The following variables are used in this project, but they are set to NOTFOUND. Please set them or make sure they are set and tested correctly in the CMake files: ZBAR_LIBRARIES linked by target "zbar_opencv" in directory /home/surabhi/opencv-zbar -- Configuring incomplete, errors occurred! See also "/home/surabhi/opencv-zbar/CMakeFiles/CMakeOutput.log".
然后，我在CMakeCache.txt中进行了两个更改，如下所示
//Path to a file.
ZBAR_INCLUDE_DIR:PATH=/usr/include/zbar
//Path to a library.
ZBAR_LIBRARIES:FILEPATH=/usr/lib/libzbar.so
因为设置为
NOTFOUND。然后没有错误
-- Found ZBAR: /usr/lib/libzbar.so -- Configuring done -- Generating done -- Build files have been written to: /home/surabhi/opencv-zbar
但是当我运行
make时它给出了错误:
fatal error: zbar.h: No such file or directory #include <zbar.h> ^ compilation terminated.
我不明白为什么会收到此错误，因为它说当我运行
cmake时发现了ZBAR 。提前致谢
最佳答案
您实际上需要在CMakeLists.txt中的某处实际使用include dirs，以便CMake知道您实际上要使用这些include路径。
例子:include_directories(${ZBAR_INCLUDE_DIR})
或更现代的推荐方式:target_include_directories(zbar_opencv PRIVATE ${ZBAR_INCLUDE_DIR})
