# Toplevel Makefile for the Modular C++ Build System
#=========================================================================
# Please read the documenation in 'mcppbs-doc.txt' for more details on
# how the Modular C++ Build System works. For most projects, a developer
# will not need to make any changes to this makefile. The key targets
# are as follows:
#
#  - default   : build all libraries and programs
#  - check     : build and run all unit tests
#  - install   : install headers, project library, and some programs
#  - clean     : remove all generated content (except autoconf files)
#  - dist      : make a source tarball
#  - distcheck : make a source tarball, untar it, check it, clean it
#  - distclean : remove everything
#

#-------------------------------------------------------------------------
# Basic setup

# Remove all default implicit rules since they can cause subtle bugs
# and they just make things run slower

# subprojects defining a certain set of make variables which are all
# prefixed with the subproject name. Since subproject names can have
# dashes in them (and the make variables are assumed to only use
# underscores) the template takes two arguments - one with the regular 
# subproject name and one with dashes replaced with underscores.

# Arguments:
#  $(1) : real subproject name (ie with dashes)
#  $(2) : normalized subproject name (ie dashes replaced with underscores)

# system will create a library for this subproject with just the
