Ubuntu 14.04: compile DCMTK 3.6.1 (development snapshot)

Get latest version from: http://dicom.offis.de/download/dcmtk/snapshot/ At the time of writing this could be done to compile latest version of the dcmtk:

	# The gist shows how to compile latest development snaphost of DCMTK 3.6.1
	# in Ubuntu 14.04. The version of the dcmtk avaliable in ubuntu's repositiries
	# is 3.6.0, which is from 2011. The gist also shows how to setup include
	#and lib folders so thatwe can use them to write our own C++ programs
	# using the develpment version.
	# first need to install required packages
	sudo apt-get install build-essential cmake libpng12-dev libtiff5-dev libxml2-dev libjpeg8-dev zlib1g-dev libwrap0-dev libssl-dev
	# where to install DCMTK
	export DCMTK_PREFIX=~/dcmtk361
	# download latest development snapshot of the dcmtk. At the time of writing it was dcmtk-3.6.1_20150217.tar.gz
	# for latest development versions please go to: http://dicom.offis.de/download/dcmtk/snapshot/
	wget http://dicom.offis.de/download/dcmtk/snapshot/dcmtk-3.6.1_20150217.tar.gz
	# unpack the archive
	tar xzvf dcmtk-3.6.1_20150217.tar.gz
	# go into the unpacked archive
	cd dcmtk-3.6.1_20150217/
	# run cmake to produce make file (alrenative to using ./configure --prefix=$DCMTK_PREFIX)
	cmake -DCMAKE_INSTALL_PREFIX=$DCMTK_PREFIX
	# compile
	make all
	# install into prefix folder
	make install
	# as a result of the above commands the follwoing folders should be created in the $DCMTK_PREFIX
	# bin, etc, include, lib, share
	# optional to clean the dcmtk-3.6.1_20150217 from the files created
	# during compilation.
	# make clean
	#----- READ BELOW when using ./configure --prefix=$DCMTK_PREFIX instead of cmake ----#
	# when ./configure --prefix=$DCMTK_PREFIX is used to configure the dmckt for
	# compilation and installation, the execution of the "make install" for
	# this development snapshot version wont produce $DCMTK_PREFIX/lib and $DCMTK_PREFIX/include
	# directories with header and library files required when wanting to write C++11 that uses
	# this snapshot version. Thus, we need to create them ourselfs.
	if false; then
	# Copy dmcktk library files that were compilied into our $DCMTK_PREFIX/lib folder
	mkdir $DCMTK_PREFIX/lib
	find . -name "*.a" -exec sh -c 'echo "Copying ${0}"; cp -Rp "${0}" $DCMTK_PREFIX/lib' {} \;
	# Now do the same but for header files.
	mkdir $DCMTK_PREFIX/include
	find . -type d -name "dcmtk" -exec sh -c 'echo "Copying ${0}"; cp -Rp "${0}" $DCMTK_PREFIX/include/' {} \;
	fi
