getPluginCreator could not find plugin DCNv2 version 1

[XinnWang]

Hi~ Thanks for sharing! I try to convert onnx to trt model, so i deleted all caffe related code, and only used onnx related code. i got following error when running the code:

[08/14/2020-22:29:07] [E] [TRT] INVALID_ARGUMENT: getPluginCreator could not find plugin DCNv2 version 1
DCNv2 plugin was not found in the plugin registry!While parsing node number 136 [Plugin]:

Any helps or suggestions ? Thanks.

btw, i tried your code, it works fine. but after i change the makefile to cmake, it cannot find any plugin( no MReLU no HSwish no DCNv2). My CMakeLists is :

cmake_minimum_required(VERSION 2.8)
project(demo)

@XinnWang how did you solve this problem ? can you share your solution? thx

Remove "CUDA_ADD_LIBRARY". Add .cu files to "SOURCE_FILES", change "add_executable" to "cuda_add_executable" worked for me.
