Description

This lets the hogmaker (re)build the hogfile only if

• the hog doesn't exist
• the hogmaker executable is newer than the hog
• the inputs source file is newer than the hog
• any of the input files is newer than the hog

otherwise only "Already up to date" is printed.

In the build process this

• reduces the build log spamming by hogmaker, especially in repeated builds where the hog doesn't change
• reduces the filesystem io because the hog isn't overwritten with the same content all the time
• keeps the hog timestamp as old as possible

Also some unused code is removed from the hogmaker.

I would like to retain ability to generate hog file no matter of what in cmd-line. Still, I understand your intentions and can propose alternative based on properly cmake dependencies detection. In result all hog files will be generated only if any of packed files was changed.

That'd be great. I'd prefer a CMake based solution which integrates into the build system more nicely.

I'm closing this PR because we have a better CMake based solution in #637.
