#  building HepMC with cmake
#-------------------------------------------------------------

This package requires cmake 2.6 or later.

#-------------------------------------------------------------
#  installing from a source code tar ball
#-------------------------------------------------------------

Unwind the source code tar ball in some relevant directory.
Determine where the files will be installed.
Create a build directory that is NOT in the source code directory tree.
Make sure cmake is in your path.

cd <build_directory>

cmake -DCMAKE_INSTALL_PREFIX=<install_dir> <source_code_dir>
   (Note that files will be installed under /usr/local if you do not 
    specify a prefix.)
make
   (Build temporary copies of libraries and executables.)
make test
   (Run the tests.)
make install
   (Copy libraries, headers, executables, etc. to relevant 
    subdirectories under <install_dir>.)

#-------------------------------------------------------------
#  cmake options
#-------------------------------------------------------------


-DCMAKE_INSTALL_PREFIX=/install/path
-DCMAKE_BUILD_TYPE=Debug|Release|RelWithDebInfo|MinSizeRel
-Dbuild_docs:BOOL=ON
 
#-------------------------------------------------------------
# building documents
#-------------------------------------------------------------

Documents are not built or installed automatically.  
If you wish to build and install the documents, 
add -Dbuild_docs:BOOL=ON to your cmake command.   
Documents will then be built during the normal build.
You will need to have latex in your path.

# building from svn
#-------------------------------------------------------------

To work with a tagged branch:
svn co svn+ssh://svn.cern.ch/reps/hepmc/tags/HEPMC_02_06_01

To work with the head:
svn co svn+ssh://svn.cern.ch/reps/hepmc/trunk HepMC 

You may also download directly from the online browser
http://svnweb.cern.ch/world/wsvn/hepmc/

Now continue with directions as if you unpacked a source code tarball.
