#dg`make.flags` Several variables can be set in order to control what to build and what dependencies to enable, these can be set either in the environment, for example: <?
# ENABLE_XXX=false make # Set flag for single command, or
# export ENABLE_XXX=false # export flag in environment and
# make # reuse exported flags.
#?>Or by directly editing the file ``common/flags.mk``.
export ENABLE_DIM ?=true
export ENABLE_MON ?=true
export ENABLE_HWLOC ?=true
export ENABLE_DOCRA ?=true
#dg`make.flags`1 _ The following dependency flags are available: _
# ENABLE_DIM::
# Whether to include support for http://cern.ch/dim[DIM]. Default: *true*.
# ENABLE_MON::
# Whether to include the interface for DQMP (Data Quality Monitor and Presenter). Default: *true*.
# ENABLE_HWLOC::
# Whether to include support for the https://www.open-mpi.org/projects/hwloc[hwloc library] (will try to schedule threads processing data from a PCIe40 board on a core closest to the corresponding PCIe root complex). Default: *true*.
# ENABLE_DOCRA::
# Whether to generate the documentation (HTML and man pages). Requires docra and asciidoctor installed. Default: *true*.
export ENABLE_DAQ40 ?=true
export ENABLE_AMC40 ?=true
export ENABLE_CCPC40 ?=false
export ENABLE_PCIE40 ?=true
#dg`make.flags`2 _ The following flags can be used to build only a subset of the targets: _
# ENABLE_DAQ40::
# Build tools and libraries that are common to both AMC40 and PCIe40 setups. Default: *true*.
# ENABLE_AMC40::
# Build tools and libraries specific to the AMC40 board. Default: *true*.
# ENABLE_CCPC40::
# Build tools and libraries specific to the AMC40 CCPC module. Default: *false*.

#dg`make.sub` Each subfolder containing a ``Makefile`` can be build individually by simply issuing ``make`` from there. Dependencies on targets built in other subfolders will be built automatically. This can be used during development to quickly iterate on a single subproject.
# By default, a sub-project ``Makefile`` implements at least the following targets: _
# *default*::
# Builds all library and executable targets.
# *install*::
# Copies installable files to their destination.
# *uninstall*::
# Removes files copied by both *install* and *maninstall*.
# *man*::
# Builds man pages.
# *maninstall*::
# Installs man pages under ``$(PREFIX)/share/man``.
# *clean*::
# Cleans build directory and deletes final targets.
# *depclean*::
# Makes the *clean* target in every dependency of this subproject.
