I'm running Centos 7 and I want Icemon for icecc. If there is a package I can install, great, but I don't know of one, so I'm attempting to build it from scratch and that relies on cmake.My missing packages include:Qt5CoreQt5GuiQt5WidgetsQt5IcecreamAnd optionally:Docbook2XI've installed Qt5 Base and Qt5 GUI through yum, so I'm perplexed how that hasn't satisfied the requirements. I've built and installed Icecream (and configured it as a service) so I don't know why it can't find the requisite library and header files. Icecream also depends on Docbook2X for it's man pages (meaning I don't have them installed, either), and because it doesn't exist as an available package, I've only just downloaded the source for that; haven't tried building it yet.I am not an IT guy or a DevOp (yet), I'm just a dev trying to cut my teeth on Linux beyond vim and gcc (the only two things I've ever known on this platform).Are there Centos 7 friendly packages for these things?Or how do I resolve this misconfiguration?This is the output:[mred@matt icemon]$ cmake .-- Could NOT find Docbook2X (missing:  DOCBOOK_TO_MAN_EXECUTABLE) -- -- The following OPTIONAL packages have been found: * Git * Doxygen , Doxygen documentation generator   Needed for generating API documentation (make doc)-- The following REQUIRED packages have been found: * Qt5Core * Qt5Gui (required version >= 5.6.0) * Qt5Widgets * Qt5 (required version >= 5.2.0) * Icecream , Package providing API for accessing icecc information.
