CMake Warning at CMakeLists.txt:42 (add_library):
Cannot generate a safe runtime search path for target rasterise because
files in some directories may conflict with libraries in implicit
directories:

runtime library [libEGL.so.1] in /usr/lib/x86_64-linux-gnu may be hidden by files in:
  /usr/lib/nvidia-410

Some of these libraries may not be found correctly.

Note that this is a warning not an error; sometimes DIRT will still work when it happens.

The warning means you have two versions of OpenGL, system and nvidia, and they aren't "tied together" by GLVND. To avoid the warning, you need to tell cmake not to look in /usr/lib/x86_64-linux at all when searching for OpenGL libraries, which can't be done (AFAIK) without modifying FindOpenGL itself.

If it does crash at runtime (because system libEGL is picked up at runtime instead of nvidia's), you can try with LD_PRELOAD=/usr/lib/nvidia-410/libEGL.so python square_test.py.

If that fails, please run

import dirt.rasterise_ops
import subprocess
subprocess.call(['ldd', dirt.rasterise_ops._lib_path + '/librasterise.so'])

and paste the output here.

This warning will cause the core dumped error when running the testing code
i just solved this by
cmake ../csrc/ -D_OPENGL_LIB_PATH=/usr/lib/nvidia-410 -DCMAKE_LIBRARY_PATH=/usr/lib/nvidia-410

thank you!
