# find_package(Armadillo REQUIRED)

# ::
|

# ARMADILLO_FOUND - set to true if the library is found

# 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")

# UNIX paths are standard, no need to write.
