Updated Blender for version 2.74

Blender è arrivato alla versione 2.74. Ho deciso questa volta di compilare la versione sorgente anzichè usare il compilato distribuito da blender.org e utilizzato da slackbuilds.org.

Slackbuilds.org offre tutti i pacchetti che servono, queste le dipendenze usate:

• cudatoolkit per usare cycles con la GPU
• opencolorio (che richiede python3 che è anche obbligatorio per Blender)
• openimageio (che richiede opencv il quale in presenza di CUDA lo usa nella compilazione)
• opencollada (facoltativo)
• lapack(facoltativo)
• numby3 (facoltativo)
• jemalloc (facoltativo)

Opencollada è stato aggiunto da poco su slackbuilds ed è stato questo a spingermi a provare a compilare l’intero pacchetto. Non sto trovando nessun limite degno di nota la momento. Per questa volta lo script lo allego al post perchè non ho ancora deciso come pubblicarlo sul repository git.
