# By default, the library and the encoder is configured for only one output bit
# depth. Meaning, one has to rebuild libx265 if (s)he wants to produce HEVC
# files with a different bit depth, which is annoying. However, upstream
# supports proper namespacing for 8bits, 10bits & 12bits HEVC and linking all
# that together so that the resulting library can produce all three of them
# instead of only one.
# The API requires the bit depth parameter, so that libx265 can then chose which
# variant of the encoder to use.
# To achieve this, we have to build one (static) library for each non-main
# variant, and link it into the main library.
# Upstream documents using the 8bit variant as main library, hence we do not
# allow disabling it: "main" *MUST* come last in the following list.
