Installing CHAP tool in combination with GROMACS

GROMACS version:
GROMACS modification: Yes/No
Here post your question:
i want to do some analysis on membrane bound protein. i want to use CHAP tool for trajactory analysis. But while installing CHAP i am getting error

CMake Error at cmake/Modules/FindGROMACS/FindGROMACS.cmake:71 (find_package):
Could not find a configuration file for package “GROMACS” that is compatible with requested version “2016”.

The following configuration files were considered but not accepted:

/usr/local/gromacs/share/cmake/gromacs/gromacs-config.cmake, version: 5.1

The user manual for CHAP installation says
" The libgromacs library of the Gromacs molecular dynamics engine in version 2016 or higher. Comprehensive installation instructions for Gromacs can be found here. Please note that for using Gromacs as a library, the underlying FFTW libray may not be installed automatically, i.e. you need to set -DGMX_BUILD_OWN_FFTW=OFF when running CMake during the Gromacs installation."

my earlier gromacs installation used this statement “cmake … -DGMX_BUILD_OWN_FFTW=ON -DREGRESSIONTEST_DOWNLOAD=ON”
Do i need to reinstall gromacs with OFF to troubleshoot this error?
