Issue compiling inference-tutorials-generic samples

It says it cant find gflags but I know its installed to the latest version.

Greetings,

Did you try to uninstall and re-install your cmake? (CMake 3.4 OR Higher)

You can refer here for CMake installation: https://cmake.org/download/

If you are using Windows, it's better to go with .msi

Do let me know if the problem still persist after the re-installation

Sincerely,

Iffa

Hi, I ran into the exact same problem when I make the step_1 demo. I tried reinstall cmake but problem remains.

It turned out that the newest version of openvino stores the gflag file in the "/opt/intel/openvino_2020.3.194/deployment_tools/inference_engine/share/../samples/cpp/thirdparty/gflags" directory. 

You need to configure the cmake file in the cmake directory:

~/tutorials/inference-tutorials-generic/face_detection_tutorial/cmake$   gedit CMakeLists_common.cmake

replace line 29 with the following code:

set(InferenceEngine_Samples_DIR "$ENV{InferenceEngine_DIR}/../samples/cpp" )

Hopes it solves your problem~
