/** \class cmGlobalUnixMakefileGenerator3
* \brief Write a Unix makefiles.
*
* cmGlobalUnixMakefileGenerator3 manages UNIX build process for a tree
The basic approach of this generator is to produce Makefiles that will all
be run with the current working directory set to the Home Output
directory. The one exception to this is the subdirectory Makefiles which are
created as a convenience and just cd up to the Home Output directory and
invoke the main Makefiles.
The make process starts with Makefile. Makefile should only contain the
targets the user is likely to invoke directly from a make command line. No
internal targets should be in this file. Makefile2 contains the internal
targets that are required to make the process work.
Makefile2 in turn will recursively make targets in the correct order. Each
target has its own directory <target>.dir and its own makefile build.make in
that directory. Also in that directory is a couple makefiles per source file
used by the target. Typically these are named source.obj.build.make and
source.obj.build.depend.make. The source.obj.build.make contains the rules
for building, cleaning, and computing dependencies for the given source
file. The build.depend.make contains additional dependencies that were
computed during dependency scanning. An additional file called
source.obj.depend is used as a marker to indicate when dependencies must be
rescanned.
Rules for custom commands follow the same model as rules for source files.
