# Our unit tests on Android repeatedly close/open the vulkan validation layers.
# This causes issues with issues with thread_local variables and overall performance.
#
# To run our tests without issue we can inform the linker to not unload VVL at runtime.
# This will prevent VVL from being unloaded by dlclose which will avoid the issue.
