Change log: v3: * Limit the use of find_path() to checking headers installed by the kernel-headers package only * Add status summary when DRM headers are not found * Rework how dmabuf_alloc.c or dmabuf_alloc_stub.c is selected v2: https://www.spinics.net/lists/linux-rdma/msg99838.html * Use pgk_check_modules() to check libdrm configuration instead of calling pkg-config directly * Put all the DRM header checking logic in CMakeLists.txt * Use a seperate source file for dma-buf allocation stubs * Remove the definition of HAVE_DRM_H from config.h * Add space between the acronym and the full name v1: https://www.spinics.net/lists/linux-rdma/msg99815.html * Fix compilation warnings for 32bit builds * Cosmetic improvement for dma-buf allocation routines * Add check for DRM headers This series fixes a few issues related to the dma-buf support. It consists of three patches. The first patch fixes a compilation warning for 32-bit builds. Patch 2 renames a function parameter and adds full name to an acronym. Patch 3 adds check for DRM headers.
