# 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_DEFINITIONS``
|
||
|
|
# 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.
