Tons of warnings when use Eigen and CUDA concurrently.
Hi, I used both CUDA (version 11) and Eigen (the latest version) concurrently on Linux. I used Eigen in the **host side**. I just included Eigen and cuda in my main.cu file, like:
`#include <Eigen/Dense>`
`#include <cuda_runtime.h>`
My cmakelist file is like:
`cmake_minimum_required (VERSION 3.5)`
`project (demo)`
`FIND_PACKAGE(CUDA REQUIRED)`
`if (NOT CUDA_FOUND)`
` message(STATUS "CUDA not found. Project will not be built.")`
`endif(NOT CUDA_FOUND)`
`##include and link to other libraries`
`INCLUDE_DIRECTORIES(Eigen path)`
`CUDA_ADD_EXECUTABLE(main ${PROJECT_SOURCE_DIR}/src/main.cu OPTIONS -arch=sm_60)`
`target_link_libraries (main otherlibraries)`
`if ( CMAKE_COMPILER_IS_GNUCC )`
` set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -Wall -Wextra -Wmaybe-uninitialized")`
`endif()`
`if ( MSVC )`
` set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} /W4 -Wmaybe-uninitialized")`
`endif()`
The compile is successful but tons of warnings occur, like
`Eigen/src/Geometry/Quaternion.h(448): warning: __device__ annotation is ignored on a function("Map") that is explicitly defaulted on its first declaration
`
**How can I silence these warnings? I think they do not yield negative effects since I just use Eigen in host side.**
