CMakeList 中应包含哪些模块.txt以进行近似最近邻搜索?

What modules should be included in CMakeList.txt for Approximate Nearest Neighbor Searching?

我已经编译了ANN库，需要在C++文件中使用它进行分割评估

我已经设置了CMakeList.txt，它使用ITK和ANN库，如下所示：

PROJECT(EvaluateSegmentationResult)
cmake_minimum_required(VERSION 3.14)
set(ANN_LIB /home/user/tools/ann_1.1.2/lib/)
set(ANN_PATH /home/user/tools/ann_1.1.2/include/)
#FIND_PACKAGE(ITK)
find_package(ITK COMPONENTS
ITKBinaryMathematicalMorphology
ITKCommon
ITKIOImageBase
ITKImageFunction
ITKImageGrid
ITKImageIntensity
ITKMathematicalMorphology
ITKThresholding
ITKImageIO
)
IF(ITK_FOUND)
INCLUDE(${ITK_USE_FILE})
ELSE(ITK_FOUND)
MESSAGE(FATAL_ERROR
"ITK not found. Please set ITK_DIR.")
ENDIF(ITK_FOUND)
FIND_PATH(ANN_PATH NAMES ANN)
FIND_LIBRARY(ANN_LIB NAMES ann PATHS ${ANN_PATH})
INCLUDE_DIRECTORIES(${ANN_PATH})
ADD_EXECUTABLE( EvaluateSegmentationResult EvaluateSegmentationResult.cpp)
#TARGET_LINK_LIBRARIES( EvaluateSegmentationResult ITKIO ITKBasicFilters ITKCommon ${ITK_LIBRARIES} ${ANN_LIB})
TARGET_LINK_LIBRARIES( EvaluateSegmentationResult ${ITK_LIBRARIES} ${ANN_LIB})

但是，一旦我编译C++文件，它就会引发错误：

/home/user/tools/EvaluationSourceCode/EvaluateSegmentationResult.cpp:86: undefined reference to `annAllocPts(int, int)'
/home/user/tools/EvaluationSourceCode/EvaluateSegmentationResult.cpp:95: undefined reference to `ANNkd_tree::ANNkd_tree(double**, int, int, int, ANNsplitRule)'

/home/user/tools/EvaluationSourceCode/EvaluateSegmentationResult.cpp:176: undefined reference to `annDeallocPts(double**&)'

似乎问题与链接库有关。 我应该在CMakeList.txt中添加任何特定的行或模块吗？

这些方法是在 ANN.lib 本身中定义的，因此您不会错过添加任何库。在find_library调用中作为 PATH 参数传递的 ${ANN_PATH} 变量指向标头包含文件夹。您应该让它指向包含库的文件夹，并在继续target_link_libraries调用之前执行 if 检查以查看是否已找到它。

我可以通过在target_link_libraries()调用中添加-lANN -LlibANN来解决问题：

TARGET_LINK_LIBRARIES( EvaluateSegmentationResult ${ITK_LIBRARIES} -lANN -LlibANN)
