# - Find Armadillo
# Find the Armadillo C++ library
#
# Using Armadillo:
# find_package(Armadillo REQUIRED)
# 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")
