# FindArmadillo

Finds the Armadillo C++ library:

    find_package(Armadillo [<version>] [...])

Armadillo is a library for linear algebra and scientific computing.

Added in version 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`

  Added in version 3.3.

  Boolean indicating whether the (requested version of) Armadillo library was found.

`Armadillo_VERSION`

  Added in version 4.2.

  The version of Armadillo found (e.g., `14.90.0`).

`Armadillo_VERSION_NAME`

  Added in version 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 since version 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  Deprecated since version 4.2: Superseded by the `Armadillo_VERSION`.

  The version of Armadillo found.

`ARMADILLO_VERSION_MAJOR`

  Deprecated since version 4.2: Superseded by the `Armadillo_VERSION`.

  Major version number.

`ARMADILLO_VERSION_MINOR`

  Deprecated since version 4.2: Superseded by the `Armadillo_VERSION`.

  Minor version number.

`ARMADILLO_VERSION_PATCH`

  Deprecated since version 4.2: Superseded by the `Armadillo_VERSION`.

  Patch version number.

`ARMADILLO_VERSION_NAME`

  Deprecated since version 4.2: Superseded by the `Armadillo_VERSION_NAME`.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:

    find_package(Armadillo REQUIRED)

    if(Armadillo_FOUND AND NOT TARGET Armadillo::Armadillo)
      add_library(Armadillo::Armadillo INTERFACE IMPORTED)
      set_target_properties(
        Armadillo::Armadillo
        PROPERTIES
          INTERFACE_LINK_LIBRARIES "${ARMADILLO_LIBRARIES}"
          INTERFACE_INCLUDE_DIRECTORIES "${ARMADILLO_INCLUDE_DIRS}"
      )
    endif()

    add_executable(foo foo.cc)
    target_link_libraries(foo PRIVATE Armadillo::Armadillo)
