cl “C:\Users\Dell-9710\Documents\Qt\R3D\R3D_LL\Hello\GetSdkVersionSample.cpp” /nologo /W3 /O2 /D NDEBUG /EHsc /MD /I"C:\Users\Dell-9710\Documents\Qt\R3D\R3D_LL\Hello" /link “C:\Users\Dell-9710\Documents\Qt\R3D\R3D_LL\Hello\R3DSDK-2017MD.lib” /out:MainCheckSdkVersion.exe

This is using the cl compiler (MSVC). In your CMake example you are using g++. That is likely the reason it can’t find symbols from your R3DSDK-2017MD.lib library to link. You need to use cl and not g++. To do that with CMake make sure you run CMake from a command prompt where the compiler is initialized correctly by running vcvars.bat.
