libJPEG v9d (a.k.a. 9.2) sources for Casio Graph 90+E and Prizm CG10/20

Need to have a fully working gcc toolchain for SH3/SH4 architecture.

You can use the giteapc install Slyvtt/cJPEG command to get an automatic install

Using in a program

With CMake

find_package(cJPEG 9.2 REQUIRED)
target_link_libraries(<TARGET> PRIVATE cJPEG::cJPEG)

With make, the following steps are not automatically done, so please proceed with the following manipulations :

copy the library libcJPG.a into your SH3/SH4 compiler lib folder
copy header files (jpeglib.h, jconfig.h, jmorecfg.h and jerror.h ) contained in the folder into the include folder of the SH3/SH4 compiler
link with -lcJPEG

In the C/C++ sources, add #include <jpeglib.h> (you may also add #include <jerror.h>)
