What seems to be happening is some kind of bad path construction or bad interpretation by the makefile.

Describe the expected behavior

Media SDK should build normally.

Debug information

• What's libva/libva-utils/gmmlib/media-driver/Media SDK version?: 22.6.1
• Could you confirm whether GPU hardware exist or not by ls /dev/dri?: No
• Could you attach dmesg log if it's GPU hang by dmesg >dmesg.log 2>&1?: No
• Could you provide vainfo log if possible by vainfo -a >vainfo.log 2>&1?: No
• Could you provide strace log if possible by strace YOUR_CMD >strace.log 2>&1?: No
• Could you provide libva trace log if possible? Run cmd export LIBVA_TRACE=/tmp/libva_trace.log first then execute the case. : No
• Media SDK tracer output (https://github.com/Intel-Media-SDK/MediaSDK/blob/master/tools/tracer/README.md)? : No
• Do you want to contribute a PR? (yes/no): No
