Compilation with patched Gromacs-2025-2 (and -1) gives error

[StefanGIT]

I downloaded plumed from github, configured as follows:
./configure --enable-modules=+maze --prefix ~/software/plumed2-maze --disable-mpi |tee configure-out.log
and compiled with gcc.

Then i downloaded gromacs-2025-2 (also tried 2025-1), patched it with plumed patch -p, run cmake as follows:
cmake .. -DGMX_BUILD_OWN_FFTW=ON -DCMAKE_INSTALL_PREFIX=~/software/plumed2-maze/gromacs-2025.2-bin/ -DGMX_GPU=CUDA -DGMX_USE_PLUMED=ON -DGMX_MPI=OFF

and then make install. During this i get the following error:
