| If you want to guarantee that the Eigen code that you are #including is licensed |
| under the MPL2 and possibly more permissive licenses (like BSD), #define this |
| preprocessor symbol: |
| EIGEN_MPL2_ONLY |
| For example, with most compilers, you could add this to your project CXXFLAGS: |
| -DEIGEN_MPL2_ONLY |
| This will cause a compilation error to be generated if you #include any code that is |
| LGPL licensed. |
