Subject: [PATCH] Use static drm and drm_amdgpu for static builds

This commit was ported from old repo.
Original author: Ranjith Ramakrishnan <Ranjith.Ramakrishnan@amd.com>

For static builds use drm and drm_amdgpu static libraries for linking.

Created a separate cmake target file and static library for static use case

The config file will include the respective target file based on
BUILD_SHARED_LIBS.

Default target file will be the one where drm and libdrm_amdgpu shaed libraries
are linked.

Applications using statically linked cmake targets of hsakmt should install the
required static libraries before building.
