MinGW-w64 compilation problem

[DJPatron]

Hello! This is my cmake parameters (I'm using MinGW to cross-compile it onto Windows x64 under Ubuntu 20):

cmake -DCMAKE_SYSTEM_NAME=Windows \ -DCMAKE_C_COMPILER=x86_64-w64-mingw32-gcc \ -DCMAKE_CXX_COMPILER=x86_64-w64-mingw32-g++ \ -DOPENSSL_ROOT_DIR=/home/test/openssl-OpenSSL_1_1_1l \ -DCUDA_TOOLKIT_ROOT_DIR=/usr/bin/nvcc \ -DOpenCL_LIBRARY=/usr/lib/x86_64-linux-gnu/ \ -DCUDA_CUDART_LIBRARY=/usr/lib/x86_64-linux-gnu/stubs \ -DOPENSSL_LIBRARIES=/usr/lib/x86_64-linux-gnu/ ..

Got some warnings after it:

When make, it shows:

Please, tell me what needs to be fixed to remove these errors?
