@murzic4
The changes are OK. But you have to commit the changed cpprest samples [ApiClient.cpp, ApiClient.h ]

You need to run cmake with the correct CPPREST_ROOT variable
For example on my PC, I go to cpprest petstore folder and create directory build and go there, then
cmake .. -DCPPREST_ROOT=/usr/include/cpprest

Can you please commit ApiClient.cpp, ApiClient.h after running the script?
