Haikuporter is a python script that eases the building of packages for Haiku on Haiku.  This task is to add support to Haikuporter so that if it is trying to build a package that needs cmake installed, but it isn't, that Haikuporter will automatically call "installoptionalpackage cmake".  It already does this for cvs, git and others.

 See this GCI 2010 completed task for examples of how this was done for git and others: https://google-melange.appspot.com/gci/task/view/google/gci2010/7067225
