我有点绝望:对于我的学习,我需要与Eigen和CMake合作.我能够使用Eigen,如果我将整个库复制到我的编译器默认查找的目录中,但是一旦我尝试通过它找到它
find_package(Eigen3 REQUIRED)
我得到以下错误:
CMake Error at /usr/share/cmake/Modules/FindPackageHandleStandardArgs.cmake:148 (message):
Could NOT find Eigen3 (missing: EIGEN3_INCLUDE_DIR EIGEN3_VERSION_OK)
(Required is at least version "2.91.0")
Call Stack (most recent call first):
/usr/share/cmake/Modules/FindPackageHandleStandardArgs.cmake:388 (_FPHSA_FAILURE_MESSAGE)
FindEigen3.cmake:76 (find_package_handle_standard_args)
CMakeLists.txt:8 (find_package)
-- Configuring incomplete, errors occurred!
现在我搜索了解决方案,但我尝试过的所有(也是stackoverflow上的那些:
查找包Eigen3 for CMake
或
CMake找不到Eigen3)都不起作用.我的Eigen版本(根据Macros Core/util/Macros.h)是3.2.5.我保留了Eigen目录/usr/local/include,我使用FindEigen3.cmake了Eigen库附带的内容,我的CMakeLists.txt外观如下:
cmake_minimum_required(VERSION 2.8)
project(Test)
set(CMAKE_MODULE_PATH ${CMAKE_CURRENT_SOURCE_DIR})
find_package(Eigen3 REQUIRED)
include_directories(${EIGEN3_INCLUDE_DIR})
message("Found Eigen3 in: ${EIGEN3_INCLUDE_DIR}")
add_executable(main test.cpp)
有谁知道出了什么问题？
亲切的问候,朱利安
