# Available defines to be used when building rocdbgapi:
#
# THE_ROCK_BUILD
#
# Satisfy TheRock's dependency on Threads. Default is OFF.
#
# If set to ON, include Threads when building. This is required when
# rocdbgapi gets built within TheRock build platform due to a dependency
# coming from amd_comgr.
#
# If building on its own, this does not need to be set.
#
#
# API_TRACING
#
# Enable/Disable API tracing. Default is ON.
#
# For debugging and stepping through code, disabling API_TRACING is
# recommended.
#
#
# ENABLE_ASSERTIONS
#
# Enable/Disable assertions. Default is ON for DEBUG builds and OFF for
# non-DEBUG builds.
#
#
# BUILD_SHARED_LIBS
#
# Enable building ROCdbgapi either as a shared library or static library.
# The default is ON, which builds ROCdbgapi as a shared library.
#
#
# ROCdbgapi has the following dependencies:
#
# amd_comgr
# libbacktrace (optional)
# GIT (optional)
# Doxygen (optional)
# Threads (on request, see THE_ROCK_BUILD)
