Installation Instructions
=========================
   Since you are reading this I assume you already obtained one of the release
tarballs and successfully extracted it. The latest version of LEMON is
available at our webpage (http://lemon.cs.elte.hu/).
   In order to install LEMON from the extracted source tarball you have to
issue the following commands:
     This changes to the directory which was created when you extracted the
     sources. The x.y.z part is a version number.
     This runs the configure shell script, which does some checks and
     configuration (creates makefiles etc).
     This command compiles the non-template part of LEMON into libemon.a file.
     It also compiles the benchmark and demo programs when enabled.
     This step is optional, but recommended. It runs the test programs that we
     developed for LEMON to check whether the library works properly on your
     This command installs LEMON under /usr/local (you will need root
     privileges to be able to do that). If you want to install it to some
     other location, then pass the --prefix=DIRECTORY flag to configure in
     step 1. For example: `./configure --prefix=/home/username/lemon'
   You can pass the following flags to configure in step 1
(see ./configure --help for more):
  Change the C++ compiler to 'comp'.
  Pass the 'flags' to the compiler. For example
  CXXFLAGS='-O3 -march=pentium-m'

   Build the demo programs too.
   Do not build the demo programs (default).
   Build the benchmark programs too.
   Do not build the benchmark programs (default).
   Enable GLPK support (default). You should specify the prefix too if
   you installed GLPK to some non-standard location (e.g. your home
   directory). If it is not found, GLPK support will be disabled.
--with-glpk-includedir=DIR
   The directory where the GLPK header files are located. This is only
   useful when the GLPK headers and libraries are not under the same
   prefix (which is unlikely).
   The directory where the GLPK libraries are located. This is only
   useful when the GLPK headers and libraries are not under the same
   prefix (which is unlikely).
   Enable CPLEX support (default). You should specify the prefix too
   if you installed CPLEX to some non-standard location
   (e.g. /opt/ilog/cplex75). If it is not found, CPLEX support will be
--with-cplex-includedir=DIR
   The directory where the CPLEX header files are located. This is
   only useful when the CPLEX headers and libraries are not under the
   same prefix (e.g.  /usr/local/cplex/cplex75/include).
   The directory where the CPLEX libraries are located. This is only
   useful when the CPLEX headers and libraries are not under the same
   /usr/local/cplex/cplex75/lib/i86_linux2_glibc2.2_gcc3.0/static_pic_mt).
