I just redid the compile of linuxcnc-ethercat. Here is what I did - after ". ~/linuxcnc-dev/scripts/rip-environment"
Check the include-directories "-I." etc, you may need to add them to config.mk and realtime.mk , I don't remember the details but there were some mod needed there.
Edit: Also needed to add -L/opt/etherlab/lib to the LDFLAGS line of realtime.mk for it to find libethercat.so

Here is a short tutorial to install linuxcnc ethercat, thank Hakan and Grotius for making my life easier 
1. Installing linuxcnc image:
2. Installing etherlab master
3. Installing linuxcnc-ethercat
4. You are now can use lcec_conf and lcec.so in linuxcnc-ethercat/src folder
5. If you are using linuxcnc-dev
Reference: forum.linuxcnc.org/10-advanced-configura...at-on-raspberry-pi-4
1. Installing linuxcnc image:
Download official image: www.linuxcnc.org/iso/linuxcnc-2.8.1-pi4.zip
Flash SD card.
setting up system2. Installing etherlab master
sudo apt-get update
sudo apt-get dist-upgrade
sudo apt-get install bison flex libssl-dev
sudo apt-get install linux-headers-4.19.71-rt24-v7l+

mkdir ethercat
cd ethercat
git clone http://github.com/icshwi/etherlabmaster
make init
echo "ENABLE_CYCLES = NO" > configure/CONFIG_OPTIONS.local
make build
make install
echo "ETHERCAT_MASTER0=eth0" > ethercatmaster.local
make dkms_add
make dkms_build

# Reboot or start manually by
sudo systemctl start ethercat
# Checking ethercat
sudo systemctl status ethercat.service3. Installing linuxcnc-ethercat
sudo apt-get install linuxcnc-uspace-dev
sudo ln -s /opt/etherlab/include/*.h /usr/include/linuxcnc/
sudo ln -s /opt/etherlab/lib/lib* /usr/lib/
git clone http://github.com/sittner/linuxcnc-ethercat.git
cd linuxcnc-ethercat
make4. You are now can use lcec_conf and lcec.so in linuxcnc-ethercat/src folder
Copy lcec_conf to config folder
Copy lcec.so to usr/lib/linuxcnc/modules5. If you are using linuxcnc-dev
git clone github.com/grotius-cnc/linuxcnc-ethercat
# Set your includepath in the /configure.mk file to point to halcompile
