Using the CPU version for GLIM

[mal-hk]

I performed the source installation given in the tutorial, while setting CUDA = OFF here
https://koide3.github.io/glim/installation.html

git clone https://github.com/koide3/gtsam_points
mkdir gtsam_points/build && cd gtsam_points/build
cmake .. -DBUILD_WITH_CUDA=ON
make -j$(nproc)
sudo make install

I then also changed the config file as suggested:
If you want to try the CPU-based odometry estimation and global optimization, in config.json, set
"config_odometry" : "config_odometry_cpu.json",
"config_sub_mapping" : "config_sub_mapping_cpu.json",
"config_global_mapping" : "config_global_mapping_cpu.json",

but when building the workspace I still get this cuda related error:

~/glim_ws$ colcon build --symlink-install

could anyone explain what might the source of the error be?
