nit: We don't use prefix style commit messages for this repo anymore (we use <Verb> <something> on most our repositories; prefix is only used if the project is large enough - we had decided that extract-xiso isn't large enough).

---

nit: We also don't usually sign-off commits in the description (in fact, we don't sign-off at all).

---

Please avoid github references in the commit description as it will create ugly references and pingbacks in the future. We mostly keep our git repo separated from github (no cross-references).

---

Regarding the code change I'd have to look into the cmake install stuff as I've never used it. I'll request reviews from others who might know.

Out of curiosity: Is there any special reason why this is necessary? extract-xiso is fairly broken as discussed in #25 (comment) - for most purposes other tools will do a better job.
The primary use of it is in nxdk where it's submoduled (and most bugs can be tolerated); so at least in nxdk it wouldn't benefit from a make install (as nxdk is self-contained and not "installed").

The code change looks fine
