CMakeAddFortranSubdirectory
CMakeAddFortranSubdirectory
Use MinGW gfortran from VS if a fortran compiler is not found.
The ‘add_fortran_subdirectory’ function adds a subdirectory to a project that contains a fortran only sub-project. The module will check the current compiler and see if it can support fortran. If no fortran compiler is found and the compiler is MSVC, then this module will find the MinGW gfortran. It will then use an external project to build with the MinGW tools. It will also create imported targets for the libraries created. This will only work if the fortran code is built into a dll, so BUILD_SHARED_LIBS is turned on in the project. In addition the CMAKE_GNUtoMS option is set to on, so that the MS .lib files are created. Usage is as follows:
cmake_add_fortran_subdirectory( <subdir> # name of subdirectory PROJECT <project_name> # project name i
