CMAKE_VS_PLATFORM_TOOLSET_FORTRAN — CMake 4.3.3 Documentation

# CMAKE_VS_PLATFORM_TOOLSET_FORTRAN

Added in version 3.29.

Fortran compiler to be used by Visual Studio projects.

Visual Studio Generators support selecting among Fortran compilers that have the required Visual Studio Integration feature installed. The compiler may be specified by a field in `CMAKE_GENERATOR_TOOLSET` of the form `fortran=...`. CMake provides the selected Fortran compiler in this variable.

If the field was not specified, the default depends on the generator:

- On `Visual Studio 18 2026` and above, the default is `ifx`.

- On older Visual Studio Generators, the default is empty, which the Intel Visual Studio Integration interprets as equivalent to `ifort`.
