I personally don't agree OpenCL should be autodetected.
Currently, only the so called "system" libs are autodetected (zlib, iconv,
pthreads,
the like). Open*L, decoding/encoding libraries, and other miscellaneous
libraries
are enabled only if explicitly requested.
If we enable one by default, then there's no argument against enabling every
other
as well ("Why this one but not that other one?"), and suddenly default builds
become
bloated and automated scripts get potentially broken until adapted.
Lets keep default builds as lightweight as possible, and allow people to
explicitly
enable the functionality they require.
