Cmake could not find OpenMP_C (Autoware)

edit

Hello everyone,

I am trying to install Autoware from Source in a Drive PX2 according to the installation proposed in https://gitlab.com/autowarefoundation....

However, when compiling, Cmake cannot find OpenMP_C (missing: OpenMP_C_FLAGS OpenMP_C_LIB_NAMES) as attached.

How could I solve this issue?

• Autoware 1.12.0
• Driveworks 5.0.5
• ROS Kinetic
• Ubuntu 16.04

Thank you in advance.
