# .rst: FindPipeWire
|
|
# -------
|
|
#
|
|
# Try to find PipeWire on a Unix system.
|
|
#
|
|
# This will define the following variables:
|
|
#
|
|
# ``PIPEWIRE_FOUND`` True if (the requested version of) PipeWire is available
|
|
# ``PIPEWIRE_VERSION`` The version of PipeWire ``PIPEWIRE_LIBRARIES`` This can
|
|
# be passed to target_link_libraries() instead of the ``PipeWire::PipeWire``
|
|
# target ``PIPEWIRE_INCLUDE_DIRS`` This should be passed to
|
|
# target_include_directories() if the target is not used for linking
|
|
# ``PIPEWIRE_COMPILE_FLAGS`` This should be passed to target_compile_options()
|
|
# if the target is not used for linking
|
|
#
|
|
# If ``PIPEWIRE_FOUND`` is TRUE, it will also define the following imported
|
|
# target:
|
|
#
|
|
# ``PipeWire::PipeWire`` The PipeWire library
|
|
#
|
|
# In general we recommend using the imported target, as it is easier to use.
|
|
# Bear in mind, however, that if the target is in the link interface of an
|
|
# exported library, it must be made available by the package config file.
