hello,everyone.i met this erro. Target"Vocoder"links to target "Eigen3::Eigen" but the target was not
found.Perhaps a find_packages() call is missing for an IMPORTED target, or an ALIAS target is missing? How can i solve this,thank you

Hello, everyone!
I find solution for this problem for Ubuntu16
It seems target_link_libraries(vocoder wavernn Eigen3::Eigen) in CMakeLists.txt don't work in my version of eigen. I removed this line and use

add_definitions ( ${EIGEN3_DEFINITIONS} )
include_directories ( ${EIGEN3_INCLUDE_DIRS} )
