# Purpose:
#   Defines include paths, compilation flags, etc. to build Media SDK targets.
#
# Defined variables:
#   MFX_OMX_CFLAGS - common flags for all targets
#   MFX_OMX_CFLAGS_LIBVA - LibVA support flags (to build apps with or without LibVA support)
#   MFX_OMX_INCLUDES - common include paths for all targets
#   MFX_OMX_INCLUDES_LIBVA - include paths to LibVA headers
#   MFX_OMX_HEADER_LIBRARIES - common imported headers for all targets
#   MFX_OMX_LDFLAGS - common link flags for all targets
