After a short discussion between me and m|m on IRC, we've decided it might be a good idea to switch to using a different image library than DevIL, since it hasn't been well maintained has proven to be a bit difficult to get newer versions of MSVS situated to build it. There has been some work done on github for DevIL to try to get cmake rolling on it, so things may change for the better in the coming months.
What are some possible alternatives to DevIL?
Aside from image format decryption and loading, I'm not sure of what the needs of PCS2 is regarding image formats at this point in time, so a second question would be: What are the needs of PCS2 regarding image formats?
Ideally, the image library that we end up choosing will support cmake, or otherwise have a number of packages available for download that developers can choose to suit their particular build system.
