iCal to Remind format

ICS (iCal) events to Remind

This is a (very) basic iCal to Remind translator. I wrote it because the ones that I could find did not work very well for my purposes; specifically, I want to have a program in my pipeline that I can use to 'open' .ics files from any mail client and append a line to my reminders.

I've tested it with a number of the invitations that have been sent to me in the past, but there is definitely room for improvement.

Building

Depending on what architecture you're building this for, it should be this simple on most of them:

cmake .
make

The known good library requirements are boost 1.47 and libical version 0.46. Later or earlier versions should work, but these are the versions against which I developed.

ics2rem's Issues

build error: ‘shared_ptr’ in namespace ‘boost’ does not name a template type

Hello! I am interested in building this program but am encountering the following error.
Does anyone have any ideas or suggestions? Thank you.

$ cmake .
CMake Deprecation Warning at CMakeLists.txt:2 (cmake_minimum_required):
  Compatibility with CMake < 2.8.12 will be removed from a future version of
  CMake.

  Update the VERSION argument <min> value or use a ...<max> suffix to tell
  CMake that the project does not need compatibility with older versions.

per homebrew's Acceptable Formulae guidelines, software that wants to be in the core repo needs to be locked to a specific version.

I'll be putting this into Homebrew/homebrew-headonly until then.
