使用cmake在C++項目中包含Caffe時出錯

Question

我想在我的項目中包含caffe。這是該項目的文件夾結構：

. 
├── AUTHORS 
├── ChangeLog 
├── cmake 
│   ├── FindCaffe.cmake 
│   └── FindCUDA.cmake 
├── CMakeLists.txt

      ├── main.qml 
      ├── Page1Form.ui.qml 
      ├── Page1.qml 
      └── qml.qrc 

這裏是root/CMakeLists.txt：

    else()

endif()

文件root/src/CMakeLists.txt：

      *.cpp *.h 
      code/*.cpp code/*.h) 

set(SOURCES ${SOURCES} 
      res/assets/assets.qrc 
      res/icons/icons.qrc 
      res/qml/qml.qrc) 

add_executable(deep-app ${SOURCES}) 

target_link_libraries(deep-app 
         Qt5::Core 
         Qt5::Qml

         ${OpenCV_LIBS}

         ${CUDA_LIBRARIES}) 

set_target_properties(deep-app PROPERTIES MACOSX_BUNDLE_INFO_PLIST ${CMAKE_SOURCE_DIR}/data/Info.plist) 

install(TARGETS deep-app 
     RUNTIME DESTINATION bin 
     DESTINATION ${CMAKE_INSTALL_BINDIR}) 

的錯誤是：

CMake Error at CMakeLists.txt:55 (FIND_PACKAGE): 
    By not providing "FindCaffe.cmake" in CMAKE_MODULE_PATH this project has 
    asked CMake to find a package configuration file provided by "Caffe", but 
    CMake did not find one. 

    Could not find a package configuration file provided by "Caffe" with any of 
    the following names: 

    CaffeConfig.cmake 
    caffe-config.cmake 

    Add the installation prefix of "Caffe" to CMAKE_PREFIX_PATH or set 
    "Caffe_DIR" to a directory containing one of the above files. If "Caffe" 
    provides a separate development package or SDK, be sure it has been 
    installed. 


-- Configuring incomplete, errors occurred! 

我有set註冊Caffe_DIR和其他所需的變量。但它仍然會給出同樣的錯誤。我刪除了以前的[cmake]緩存，所以這不是問題。我無法弄清楚如何解決這個問題，我需要在項目中使用Caffe。請幫忙。

你要設置你的CMAKE_MODULE_PATH到位置，其中的cmake module文件所在的Caffe項目，這將是指向的目錄下面：

. 
├── AUTHORS 
├── ChangeLog 
├── cmake   <---------Set Caffe_DIR it to this directory 
│ ├── FindCaffe.cmake 
│ └── FindCUDA.cmake 

如果不工作，那麼你應該設置你的Caffe_DIR到上面的目錄，並確保您重新命名目錄下的文件，以下面的錯誤中提到的名稱之一：

Could not find a package configuration file provided by "Caffe" with any of 
    the following names: 

    CaffeConfig.cmake 
    caffe-config.cmake
