#.rst:
# FindLibdrm
# -------
#
# Try to find libdrm on a Unix system.
#
# This will define the following variables:
#
# ``Libdrm_FOUND``
# True if (the requested version of) libdrm is available
# ``Libdrm_VERSION``
# The version of libdrm
# ``Libdrm_LIBRARIES``
# This can be passed to target_link_libraries() instead of the ``Libdrm::Libdrm``
# target
# ``Libdrm_INCLUDE_DIRS``
# This should be passed to target_include_directories() if the target is not
# used for linking
# ``Libdrm_DEFINITIONS``
# This should be passed to target_compile_options() if the target is not
# used for linking
#
# If ``Libdrm_FOUND`` is TRUE, it will also define the following imported target:
#
# ``Libdrm::Libdrm``
# The libdrm 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.
