Dear ALL,
The purpose of my project is to use opencv in CODEBLOCKS for face identification.
The tools I am using:
Windows 10 professional french version 64 bits
CodeBlocks-16.01 mingw setup.exe
Opencv 2.4.13
CMake 3.8.2 -win64

The Cmake configuration generated the following errors. 
I am grateful for any help to move forward.
Thank you in advance for your assistance.

Best Regards
