- Moved ``<sys/capability.h>`` include inside `__linux__` guard, because all uses are similarly guarded. - <sys/capability.h> is part of an optional devel package, at least in fedora. CMake now explicitly checks that libcap devel files are available. - Added libcap to the list of install packages in .travis.yml, to make the dependency explicit. travis-ci installs the package by default, which is why this hasn't surfaced previously.
