Tests create either white or black windows without anything in them

[yurivict]

For example, cubescape-gtk4-gles creates a white window, but cubescape-gtk3-gl creates a black window.

Version: 3.4.0

Thanks for reporting. Do you have some console output you could share?
I suppose there were general errors with loading and compiling the shaders.

This usually coincides with the use of static data paths, when the example wasn't started from the root directory of the project.

You can check for the following outputs:

During CMake configuration:

Example Lib cubescape-shared-gl: using static data path (cpplocate not found)
Example Lib cubescape-shared-gles: using static data path (cpplocate not found)

During execution:

Could not load shaders in ./data/cubescape/cubescape.*.

Maybe, there are other errors, which then would be interesting to see.
