CMake error related to deprecated CACHE variables

[traversaro]

Describe the bug
Since, if I set an option variable that is deprecated, I get this error:

To Reproduce
Compile YARP master branchg setting the ENABLE_yarpcar_depthimage2 CMake option.

Expected behavior
YARP should configure correctly.

Configuration (please complete the following information):

• OS: N.A.
• yarp version: current master
• compiler: N.A.
