Note that you will need a C++ compiler and CMake installed to build the
PyNumero libraries.

Method 1
--------

One way to build PyNumero extensions is with the pyomo
download-extensions and build-extensions subcommands. Note that
`download-extensions` and `build-extensions` subcommands. Note that
this approach will build PyNumero without support for the HSL linear
solvers. ::

If you want PyNumero support for the HSL solvers and you have an IPOPT compilation
for your machine, you can build PyNumero using the build script ::

cd pyomo/contrib/pynumero/
python build.py -DBUILD_ASL=ON -DBUILD_MA27=ON -DIPOPT_DIR=<path/to/ipopt/build/>
python -m pyomo.contrib.pynumero.build -DBUILD_ASL=ON -DBUILD_MA27=ON -DIPOPT_DIR=<path/to/ipopt/build/>

Method 3
--------

You can build the PyNumero libraries from source using `cmake`. This
generally works best when building from a source distribution of Pyomo.
Assuming that you are starting in the root of the Pyomo source
distribution, you can follow the normal CMake build process ::

mkdir build
cd build
ccmake ../pyomo/contrib/pynumero/src
