### Enabling CPLEX Support
To enable CPLEX support, configure with `-DUSE_CPLEX=ON` and `-DCPLEX_ROOT=/absolute/path/to/CPLEX/root/dir`,
replacing `/absolute/path/to/CPLEX/root/dir` with the path to your CPLEX installation.
`CPLEX_ROOT` can also be defined as an environment variable rather than an option at configure time.
For ease of migration from legacy `make third_party` builds, CMake will also read the CPLEX installation path from the
`UNIX_CPLEX_DIR` environment variable, if defined.
### Enabling XPRESS Support
To enable XPRESS support, configure with `-DUSE_XPRESS=ON` and `-DXPRESS_ROOT=/absolute/path/to/XPRESS/root/dir`,
replacing `/absolute/path/to/XPRESS/root/dir` with the path to your XPRESS
installation. `XPRESS_ROOT` can also be defined as an environment variable rather than an option at configure time.
