Compile OF ob Ubuntu MATE 18.04

Hi,

I want to compile OF on my Rpi 3 B + running Ubuntu MATE 18.04:
tested with of_v20190324_linuxarmv7l_release and of_v0.10.1_linuxarmv7l_release

• “sudo apt-get update” DONE
• “sudo apt-get upgrade” DONE
• “cd scripts/ubuntu sudo ./install_dependencies.sh” DONE
  output “All packages were installed correctly”
• “sudo ./install_codecs.sh” DONE

BUT when I tap “cd scripts/linux, sudo ./compileOF.sh”, it outputs:
"
HOST_OS=Linux
checking pkg-config libraries: cairo zlib gstreamer-app-1.0 gstreamer-1.0 gstreamer-video-1.0 gstreamer-base-1.0 libudev freetype2 fontconfig sndfile openal libcurl glfw3 rtaudio gtk±3.0 libmpg123 glesv1_cm glesv2 egl
with PKG_CONFIG_LIBDIR=
Package glesv1_cm was not found in the pkg-config search path.
Perhaps you should add the directory containing glesv1_cm.pc' to the PKG_CONFIG_PATH environment variable No package 'glesv1_cm' found Package glesv1_cm was not found in the pkg-config search path. Perhaps you should add the directory containingglesv1_cm.pc’
to the PKG_CONFIG_PATH environment variable
No package ‘glesv1_cm’ found
makefileCommon/config.shared.mk:291: *** couldn’t find glesv1_cm pkg-config package or it’s dependencies, did you run the latest install_dependencies.sh?. Stop.
there has been a problem compiling Debug OF library
please report this problem in the forums

Reproduce the failure with scripts/ubuntu/install_dependencies.sh followed by scripts/linux/compileOF.sh on Ubuntu MATE 18.04 for the Raspberry Pi 3 B. Inspect the glesv1_cm dependency check at makefileCommon/config.shared.mk:291 and determine why the required pkg-config package is unavailable; done means the Debug OF library compiles successfully.
