I want to set Protobuf_INCLUDE_DIRS to a directory of my choosing, however, I am not sure how to do that.
$ locate FindProtobuf.cmake
/usr/share/cmake-3.16/Modules/FindProtobuf.cmake
I can see that in FindProtobuf.cmake, we have these:
if(Protobuf_FOUND)
set(Protobuf_INCLUDE_DIRS ${Protobuf_INCLUDE_DIR})
endif()
I want it to be set to the second option here:
$ which -a protoc
/home/mona/anaconda3/bin/protoc
/usr/local/bin/protoc
However, it is set to the first option /home/mona/anaconda3/bin/protoc despite forcing it in ~/.bashrc to second option: /usr/local/bin/protoc using below command: alias protoc=/usr/local/bin/protoc
The version that my program requires is 3.6.1 and alias protoc=/usr/local/bin/protoc assures that. However, ProtobufCMake forces the path to be /home/mona/anaconda3/bin/protoc and that version is 3.13.0.
A bit about the problem I am facing. I am using openpose and for installing it in Ubuntu 20.04, I am using CMake. It requires the protobuf version to be 3.6.1.

Not sure how exactly do what I wanted to do above, but a hack to get CMake work for OpenPose is using Python venv and comment the anaconda python activation lines in ~/.bashrc:
Now, cmake-gui .. throws no error:

Configuring done
I have this in ~/.bashrc:
# >>> conda initialize >>>
# !! Contents within this block are managed by 'conda init' !!
##__conda_setup="$('/home/mona/anaconda3/bin/conda' 'shell.bash' 'hook' 2> /dev/null)"
##if [ $? -eq 0 ]; then
## eval "$__conda_setup"
##else
## if [ -f "/home/mona/anaconda3/etc/profile.d/conda.sh" ]; then
## . "/home/mona/anaconda3/etc/profile.d/conda.sh"
## else
## export PATH="/home/mona/anaconda3/bin:$PATH"
## fi
##fi
and installed the following in Ubuntu 20.04:
$ sudo apt-get install python3
$ sudo apt-get install python3-venv
also, do this in ~/.bashrc and source it: alias python=python3
$ python -m venv ~/venv/openpose
$ source ~/venv/openpose/bin/activate
