We don't actually have the code for the shader cache just yet, but this configure machinery puts everything in place so that the shader cache can be optionally compiled in. Specifically, if the user passes no option (neither --disable-shader-cache, nor --enable-shader-cache), then this feature will be automatically detected based on the presence of a usable SHA-1 library. If no suitable library can be found, then the shader cache will be automatically disabled, (and reported in the final output from configure). The user can force the shader-cache feature to not be compiled, (even if a SHA-1 library is detected), by passing --disable-shader-cache. This will prevent the compiled Mesa libraries from depending on any library for SHA-1 implementation. Finally, the user can also force the shader cache on with --enable-shader-cache. This will cause configure to trigger a fatal error if no sutiable SHA-1 implementation can be found for the shader-cache feature. Bug fix by José Fonseca <jfonseca@vmware.com>: Fix to put conditional assignment in Makefile.am, not Makefile.sources to avoid breaking scons build. Note: As recommended by José, with this commit the scons build will not compile any of the SHA-1-using code. This is waiting for someone to write SConstruct detection of the available SHA-1 libraries, (and set the appropriate HAVE_SHA1_* variables). Reviewed-by: Matt Turner <mattst88@gmail.com>
