If you have problems downloading fftw you can install it beforehand and point cmake to where those libraries are installed.

Alternatively after configuring, find the `download-fftwBuild.cmake` file and replace its contents with below and add your path to the source files in the file download command.

```auto

cmake_minimum_required(VERSION ${CMAKE_VERSION}) # this file comes with cmake

file(DOWNLOAD "https://www.fftw.org/fftw-3.3.10.tar.gz" "<your-path-to-gromacs>/gromacs-2026.2/build/src/external/build-fftw/fftwBuild-prefix/src/fftw-3.3.10.tar.gz"
     SHOW_PROGRESS
     INACTIVITY_TIMEOUT 60
     TIMEOUT 600
     STATUS status)

list(GET status 0 status_code)
list(GET status 1 status_message)

if(NOT status_code EQUAL 0)
    message(FATAL_ERROR "Download failed (${status_code}): ${status_message}")
endif()

```
