BUG: prerelease (cmake) fails to build due to non-existence path

[anqixu]

Tested on Ubuntu 20.04.1 and ROS Noetic, Docker version 20.10.2

Commands ran:

mkdir -p /tmp/prerelease_job
cd /tmp/prerelease_job
generate_prerelease_script.py https://raw.githubusercontent.com/ros-infrastructure/ros_buildfarm_config/production/index.yaml noetic default ubuntu focal amd64 ueye_cam --level 1 --output-dir ./
./prerelease.sh

Snippet of error log:

CMake Error at /usr/share/cmake-3.16/Modules/CMakeTestCCompiler.cmake:60 (message):
  The C compiler

  is not able to compile a simple test program.

  It fails with the following output:

P.S.: prerelease.ros.org step 3 spins forever, so I had to edit the HTML to un-disable the generate button in order to obtain the prerelease commands above.
