Similar to toolchains, we now offer a way for br2-external trees to provide their libjpeg implementation, which gets included in the jpeg choice. Signed-off-by: "Yann E. MORIN" <yann.morin.1998@free.fr> Cc: Vadim Kochan <vadim4j@gmail.com> Signed-off-by: Peter Korsgaard <peter@korsgaard.com>

Libjpeg-turbo is a derivative of libjpeg that uses SIMD
|
|
instructions (MMX, SSE2, NEON) to accelerate baseline JPEG
|
|
compression and decompression on x86, x86-64, and ARM
|
|
systems.
