Automake includes some support for Objective C++.
Any package including Objective C++ code must define the output variable
OBJCXX in configure.ac; the simplest way to do this is to use
the AC_PROG_OBJCXX macro (see Particular
Program Checks in The Autoconf Manual).
A few additional variables are defined when an Objective C++ source file is seen:
OBJCXX ¶The name of the Objective C++ compiler.
OBJCXXFLAGS ¶Any flags to pass to the Objective C++ compiler.
AM_OBJCXXFLAGS ¶The maintainer’s variant of OBJCXXFLAGS.
OBJCXXCOMPILE ¶The command used to actually compile an Objective C++ source file. The file name is appended to form the complete command line.
OBJCXXLINK ¶The command used to actually link an Objective C++ program.
