ilmbase, openexr: Always apply patch on Mac, regardless of compiler.
cylemon.cmake:
- Updated repo URL
- Use --no-extra-includes to avoid extra include dirs
- For Mac builds, use --no-openmp (clang doesn't support OpenMP)
ilastik.cmake: Don't rename drtile lib (the rename is no longer needed with the latest drtile cmake script)
lemon.cmake:
- Use the hg repo instead of the tar download.
- Skip the test step, which doesn't pass in the hg repo (yikes)
- Require CMake 2.8.10, since earlier versions of ExternalProject_Add don't support hg
lemon.cmake: Use correct variable name for source tag verison.
