Clion上的目标链路特征库失败

Question

我正在尝试将特征链接到我在clion上的项目，但是打印了以下错误：

这是我的cmakelist文件，所有链接库的尝试：

cmake_minimum_required(VERSION 2.8.3)
project(planner_standalone_grasp)

set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -O0")
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -fno-diagnostics-color")
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++17")

# find all cpp files in currect directory (where CMakeLists.txt is)
file(GLOB SOURCE_FILES FILES_MATCHING PATTERN "./src/*.cpp")


include_directories(src)


add_executable(${PROJECT_NAME} main.cpp ${SOURCE_FILES})


set(EXE_LIBS
    ctop_common
    ctop_log
    ctop_util

    eigen
    crl
    crl-algorithm
    crl-loader
    crl-tsplib
    yaml-cpp
)


target_link_directories(${PROJECT_NAME} PUBLIC lib/comrob/lib/)
target_link_directories(${PROJECT_NAME} PUBLIC ctop/common/cmake-build-debug/)
target_link_directories(${PROJECT_NAME} PUBLIC ctop/log/cmake-build-debug/)
target_link_directories(${PROJECT_NAME} PUBLIC ctop/util/cmake-build-debug/)


set(EIGEN_DIR "/usr/local/include/Eigen/")
include_directories(${EIGEN_DIR})


find_package (Eigen3 3.3 REQUIRED NO_MODULE)
target_link_libraries (${PROJECT_NAME} Eigen3::Eigen)

target_link_directories(${PROJECT_NAME} PUBLIC lib/eigen/Eigen/)
target_link_directories(${PROJECT_NAME} PUBLIC /usr/local/include/Eigen/)
target_link_directories(${PROJECT_NAME} PUBLIC /usr/local/include/eigen3/Eigen/)


target_link_libraries(${PROJECT_NAME} ${EXE_LIBS})

该项目中的所有其他库都已成功链接，除了特征--这是错误消息：

任何帮助都将不胜感激！

Answer 1

根据我的经验，这个问题有两个可能的原因：

1. 没有一个名为libeigen的库。在提供的目录(target_link_directories中的目录)中。也许这条路错了？您应该知道，库文件通常不在repository...
2. there的包含目录中，而是一个名为这样的库，尽管它是为错误的平台编译的.也就是说，如果要为windows生成可执行文件，则不能链接为linux编译的库。通常您可以找到源代码并自己编译。

希望这能有所帮助。
