#
# LuaJIT configuration file.
#
# A copy of LuaJIT is maintained within Tarantool
# source. It's located in third_party/luajit.
#
# Instead of this copy, Tarantool can be compiled
# with a system-wide LuaJIT, or LuaJIT at a given
# prefix. This is used when compiling Tarantool
# as part of a distribution, e.g. Debian.
#
# To explicitly request use of the bundled LuaJIT,
# add -DENABLE_BUNDLED_LUAJIT=True to CMake
# configuration flags.
# To explicitly request use of LuaJIT at a given
# prefix, use -DLUAJIT_PREFIX=/path/to/LuaJIT.
#
# These two options are incompatible with each other.
#
# If neither of the two options is given, this script
# first attempts to use the system-installed LuaJIT
# and, in case it is not present or can not be used,
# falls back to the bundled one.
#
# Adds CMake options: ENABLED_BUNDLED_LUAJIT, LUAJIT_PREFIX
# Exports CMake defines: LUAJIT_PREFIX, LUAJIT_INCLUDE, LUAJIT_LIB
# Modifies CMAKE_CFLAGS with -I${LUAJIT_INCLUDE}
