fatal error: Eigen/Core: No such file or directory compilation terminated

I recently change my OS to the last mint cinamon. Compiling one of the library I need (and that I used to used without problem), I get this message: 

fatal error: Eigen/Core: No such file or directory compilation terminated.

I don't know what to do. Thanks for the help.

Including directory /usr/local/include/eigen3/ solved this for me.

Like this, for example:

g++ -I/usr/local/include/eigen3/ CODE.cpp -o EXECUTABLE
