# 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. |
