Fortran_MODULE_DIRECTORY — CMake 4.3.0 Documentation

# Fortran_MODULE_DIRECTORY

Specify output directory for Fortran modules provided by the target.

If the target contains Fortran source files that provide modules and the compiler supports a module output directory this specifies the directory in which the modules will be placed. When this property is not set the modules will be placed in the build directory corresponding to the target's source directory. If the variable `CMAKE_Fortran_MODULE_DIRECTORY` is set when a target is created its value is used to initialize this property.

When using one of the Visual Studio Generators with the Intel Fortran plugin installed in Visual Studio, a subdirectory named after the configuration will be appended to the path where modules are created. For example, if `Fortran_MODULE_DIRECTORY` is set to `C:/some/path`, modules will end up in `C:/some/path/Debug` (or `C:/some/path/Release` etc.) when an Intel Fortran `.vfproj` file is generated, and in `C:/some/path` when any other generator is used.

Note that some compilers will automatically search the module output directory for modules USEd during compilation but others will not. If your sources USE modules their location must be specified by `INCLUDE_DIRECTORIES` regardless of this property.
