Block averaging

GROMACS version:2019:6
GROMACS modification: No
Hi,
I am trying to use gmx analyze for the block analysis and I get this error:

Fatal error:
“This build of GROMACS was not configured with support for lmfit, so the
requested fitting cannot be performed. See the install guide for
instructionson how to build GROMACS with lmfit supported.”

I have installed gromacs with the option -DGMX_USE_LMFIT=INTERNAL,

Thanks
