# - Initialize project-specific variables
#
# This will read the dune.module file for project information and
# set the following variables:
#
# project From the Module: field
# ${project}_NAME Same as above
# ${project}_DESCRIPTION From the Description: field
# ${project}_VERSION_MAJOR From the Version: field
# ${project}_VERSION_MINOR From the Version: field also
#
# This module should be the first to be included in the project,
# because most of the others (OpmXxx.cmake) use these variables.
# for CMake >= 3.0, we need to change a few policies:
#
# - CMP0026 to allow access to the LOCATION target property
# - CMP0048 to indicate that we want to deal with the *VERSION*
# variables ourselves
# - CMP0064 to indicate that we want TEST if conditions to be evaluated
# - CMP0074 to indicate that <PackageName>_ROOT can be used to find package
# config files
