FindJPEG.cmake defines JPEG_VERSION from JPEG_LIB_VERSION (with a regexp) : it's the libjpeg ABI version chosen when configuring libjpeg (for example 62).

libjpeg-turbo >= 1.5.0 has a libjpeg.pc, which has the libjpeg-turbo version.

But does everyone use libjpeg-turbo ?
The code is still compatible with the original libjpeg (IJG), obviously using only RGB output.
