CMake Error at CMakeLists.txt:5 (project):
  No CMAKE_Fortran_COMPILER could be found.

  Tell CMake where to find the compiler by setting either the environment
  variable "FC" or the CMake cache entry CMAKE_Fortran_COMPILER to the full
  path to the compiler, or to the compiler name if it is in the PATH.

解决办法：cmake - how to solve No CMAKE_Fortran_COMPILER could be found.? - Ask Ubuntu

        it's probably missing gfortran Try installing the gfortran using the following command:

sudo apt install gfortran
