# The KERNEL_HEADER_DIR setting is required by the CMake apparently
# in order to find the DRM headers. However, the Yocto build provides
# the DRM headers via a separate recipe libdrm in order to avoid the
# kernel dependency. The CMake fails if the variable is not defined,
# so set it to an invalid value in case the build ever actually needs
# the kernel headers for something else.
