/** \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.
