build/tests issue

[ShaoYULi12]

hi~
I found that when i run ./build/tests ~Timing，the error information is
“MatterSim: Could not open skybox RGB files at: ./data/v1/scans//17DRP5sb8fy/
matterport_skybox_images/85c23efeaecd4d43a7dcd5b90137179e_skybox_small.jpg
test cases: 5 | 4 passed | 1 failed
assertions: 119188 | 119187 passed | 1 failed”.
So i download this dataset “17DRP5sb8fy”， and i try again. When i run "cmake -DEGL_RENDERING=ON ..", a new problem appears that
