64bit ports are in contrib, 32bit in compat-32 CRUX repos
I'll still keep it around, in the off chance that compat-32 repo
lags behind.

Vulkan 64bit and 32bit ports for CRUX Linux


For 64bit,
    'prt-get depinst vulkan-validation-layers'

for 32bit,
    'prt-get depinst vulkan-validation-layers-32'

After the install, use 'vulkaninfo/cube' (both 64bit and 32bit are available),
to test.
For more thorough testing, use vkquake :)
