# We require 2.8.12+ for three reasons:
|
|
# 1) CMake 3 is so common these days that it's really not a burden on the user
|
|
# to expect them to have it.
|
|
# 2) As of this writing, this is the oldest version included in a supported
|
|
# release of Ubuntu. Older versions are actually somewhat difficult to track
|
|
# down, so we don't test against them.
|
|
# 3) CMake's INTERFACE_INCLUDE_DIRECTORIES feature, which we rely on
|
|
# extensively, finally became stable in this release.
