FindArmadillo
-------------
Finds the Armadillo C++ library:
.. code-block:: cmake
find_package(Armadillo [<version>] [...])
Armadillo is a library for linear algebra and scientific computing.
.. versionadded:: 3.18
Support for linking wrapped libraries directly (see the
``ARMA_DONT_USE_WRAPPER`` preprocessor macro that needs to be defined before
including the ``<armadillo>`` header).
Result Variables
^^^^^^^^^^^^^^^^
This module defines the following variables:
``Armadillo_FOUND``
.. versionadded:: 3.3
Boolean indicating whether the (requested version of) Armadillo library
was found.
``Armadillo_VERSION``
.. versionadded:: 4.2
The version of Armadillo found (e.g., ``14.90.0``).
``Armadillo_VERSION_NAME``
.. versionadded:: 4.2
The version name of Armadillo found (e.g., ``Antipodean Antileech``).
``ARMADILLO_INCLUDE_DIRS``
List of required include directories.
``ARMADILLO_LIBRARIES``
List of libraries to be linked.
Deprecated Variables
^^^^^^^^^^^^^^^^^^^^
The following variables are provided for backward compatibility:
``ARMADILLO_FOUND``
.. deprecated:: 4.2
Use ``Armadillo_FOUND``, which has the same value.
Boolean indicating whether the (requested version of) Armadillo library
was found.
``ARMADILLO_VERSION_STRING``
.. deprecated:: 4.2
Superseded by the ``Armadillo_VERSION``.
The version of Armadillo found.
``ARMADILLO_VERSION_MAJOR``
.. deprecated:: 4.2
Superseded by the ``Armadillo_VERSION``.
Major version number.
``ARMADILLO_VERSION_MINOR``
.. deprecated:: 4.2
Superseded by the ``Armadillo_VERSION``.
Minor version number.
``ARMADILLO_VERSION_PATCH``
.. deprecated:: 4.2
Superseded by the ``Armadillo_VERSION``.
Patch version number.
``ARMADILLO_VERSION_NAME``
.. deprecated:: 4.2
Superseded by the ``Armadillo_VERSION_NAME``.
The version name of Armadillo found (e.g., ``Antipodean Antileech``).
Examples
^^^^^^^^
Finding Armadillo and creating an imported target:
.. code-block:: cmake
