find_package查找不到eigen3
Could not find apackage configuration file provided by "Eigen3" with any of the followingnames: Eigen3Config.cmake eigen3-config.cmake Add theinstallation prefix of "Eigen3" to CMAKE_PREFIX_PATH or set "Eigen3_DIR"to a directory containing one of the above files. If "Eigen3"
解决方法
将FindEigen3.cmake文件放置到源代码文件夹下的CMakeModules文件夹内即可
set(CMAKE_MODULE_PATH ${CMAKE_CURRENT_SOURCE_DIR}/CMakeModules)
FindEigen3.cmake可在eigen/cmake文件夹里面查到
