OSVR-Fove: Failed to load plugin warning

[wellLai]

The issue is similar to issue #552 with the warning of failing to load the plugin.
Below is my setup:

1. download osvr-sdk 0.6.2118 for 64-bit machine
2. download FOVE SDK 0.14.0
3. clone the osvr-fove from https://github.com/OSVR/OSVR-FOVE/tree/build-improvements
4. cmake the OSVR-FOVE project with 'Visual Studio 15 2017 Win64' config
5. run the project with 'RelWithDebInfo' and get com_Sensics_FOVE.dll plugin
6. put the plugin into directory 'C:\Program Files\OSVR\Runtime\bin\osvr-plugins-0'
7. run the osvr_server with fove config file and the result is like this:
   

The loading just keeps failing, I've tried all different settings (Visual Studio 2013, Debug config, Release config...) and not sure what the problem is.
