Vlad Zahorodnii 1fb9f6f13a Switch to SPDX license markers
The main advantage of SPDX license identifiers over the traditional
license headers is that it's more difficult to overlook inappropriate
licenses for kwin, for example GPL 3. We also don't have to copy a
lot of boilerplate text.

In order to create this change, I ran licensedigger -r -c from the
toplevel source directory.

#.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.
