Visual Studio 2017 CMake linking error (undefined reference to)

I'm working on a cross platform c++ application (windows & Linux). I'm using VS 2017 professional as my IDE and Cmake as my build tool. Code contains both c & c++ files. Currently I'm able to build the project in Windows but I'm having issues linking object files in Linux.

Tools:

1. Visual Studio Professional 2017
2. Cmake version 3.12.18081601-MSVC_2 (Windows)
3. Cmake version 3.16.1 (Linux)

The project structure below is simplified.

Build in Windows is successful. I'm able to generate executable.Finally, when I do build in Linux, the following error is generated:

I'm resolve this issue using target_link_options. But linking is still causing the issues.
