# - 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")
