# .hdr -> .ktx baker. Quite similar to qt6_add_shaders().
#
# For example, the following autogenerates the lightprobe map at build time and
# includes it in the executable under :/maps/OpenfootageNET_garage-1024.ktx:
#
# qt6_add_lightprobe_images(principledmaterial "ibl_assets"
# PREFIX
# "/"
# FILES
# "maps/OpenfootageNET_garage-1024.hdr" )
#
# In addition to PREFIX, BASE is available as well, and works like in qt6_add_resources:
# adding BASE "maps" in the above example would lead to getting :/OpenfootageNET_garage-1024.ktx
#
# OUTPUTS works like in qt6_add_shaders, allowing to specify an alternative name
# for the resource system for each entry in FILES. For example, adding
# OUTPUTS "alt/er/native/image.abc" to the above example would generate :/alt/er/native/image.abc
#
# In short, the actual file name in the resource system is
# either :/PREFIX/FILES[i]-BASE-".hdr"+".ktx" or :/PREFIX/OUTPUTS[i]
