# Find Magnum bindings |
|
# -------------------- |
|
# |
|
# Finds helper headers for the Magnum bindings. Basic usage:: |
|
# |
|
# find_package(MagnumBindings REQUIRED) |
|
# |
|
# This command tries to find Magnum bindings and then defines the following: |
|
# |
|
# MagnumBindings_FOUND - Whether Magnum bindings were found |
|
# |
|
# This command will not try to find any actual bindings. The bindings are: |
|
# |
|
# Python - Python bindings |
|
# |
|
# Example usage with specifying the components is:: |
|
# |
|
# find_package(MagnumBindings REQUIRED Python) |
|
# |
|
# For each component is then defined: |
|
# |
|
# MagnumBindings_*_FOUND - Whether the bindings were found |
|
# MagnumBindings::* - Imported target |
|
# |
|
# The package is found if the headers are found. None of the bindings expose |
|
# any library at the moment. |
|
# |
|
# Additionally these variables are defined for internal usage: |
|
# |
|
# MAGNUMBINDINGS_INCLUDE_DIR - Magnum bindings include dir (w/o dependencies) |
|
