# - Try to find Armadillo include dirs and libraries
# Usage of this module as follows:
#
# == Using Armadillo: ==
#  find_package( Armadillo RECQUIRED )
#  include_directories(${ARMADILLO_INCLUDE_DIRS})
#  add_executable(foo foo.cc)
#  target_link_libraries(foo ${ARMADILLO_LIBRARIES})
#
#=============================================================================
#
# This module sets the following variables:
#  ARMADILLO_FOUND - set to true if the library is found
#  ARMADILLO_INCLUDE_DIRS - list of required include directories
#  ARMADILLO_LIBRARIES - list of libraries to be linked
#  ARMADILLO_VERSION_MAJOR - major version number
#  ARMADILLO_VERSION_MINOR - minor version number
#  ARMADILLO_VERSION_PATCH - patch version number
#  ARMADILLO_VERSION_STRING - version number as a string (ex: "1.0.4")
#  ARMADILLO_VERSION_NAME - name of the version (ex: "Antipodean Antileech")
