# Notes on CMake: CMake builds libefp, the shared or static library,
# but not efpmd because Psi4 doesn't use it. Also not implemented
# is testing with CTest. Also, when libefp is
# compiled statically with OpenMP, will need to compile consuming
# application with OpenMP, too, or supply link library.
