Install all necessary building and development libraries viz. cmake, cpp, libcurl, libconfig, qt5, tinyxml2 for your distro. Please note that the developemnet libraries could be suffixed with either -dev (in debian-based distros) or -devel in others like (arch or voidlinux). If you come across a missing package or libraries while compiling and building as in 3 and 7 below, you ought to install those, too.
Create a directory to keep the sources:
mkdir opencast-obs-plugin-build-from-source
Change to the newly-created directory:
cd opencast-obs-plugin-build-from-source
Pull the lib-opencast-ingest source and compile with the following command (one line at a time):
git clone https://github.com/elan-ev/lib-opencast-ingest.git
cd lib-opencast-ingest/
mkdir build && cd build
cmake -DCMAKE_BUILD_TYPE=Release ..
cmake --build .
Change to the default build directory as in 1 above:
cd ../../
Pull the opencast-obs-plugin from source repo:
git clone https://github.com/elan-ev/opencast-obs-plugin.git
Make some symlinks to lib-opencast-ingest headers:
cd opencast-obs-plugin/libs/libOpencastIngest/include/
ln -s ../../../../lib-opencast-ingest/src/libOpencastIngest.h
ln -s ../../../../lib-opencast-ingest/src/libOpencastIngest.hpp
cd ../lib
ln -s ../../../..//lib-opencast-ingest/build/libOpencastIngest_static.a libOpencastIngest.a
Compile and build this plugin:
cd ../../..
mkdir build
cd build/
cmake -DCMAKE_BUILD_TYPE=Release ..
cmake --build .
You will get the following if compiled and built successfully:
You may encounter some warnings, but it does not seem to impact, so can be IGNORED(?)!
Warning related to package name mismatch:
...
CMake Warning (dev) at /usr/share/cmake-3.18/Modules/FindPackageHandleStandardArgs.cmake:273 (message):
The package name passed to `find_package_handle_standard_args` (TINYXML2)
does not match the name of the calling package (TinyXML2). This can lead
to problems in calling code that expects `find_package` result variables
(e.g., `_FOUND`) to follow a certain pattern.
Call Stack (most recent call first):
cmake/FindTinyXML2.cmake:13 (find_package_handle_standard_args)
CMakeLists.txt:69 (find_package)
This warning is for project developers. Use -Wno-dev to suppress it.

Hi,
I propose to include the following instructions (derived from my own experience described in #11) either in
README.mdor particulary in https://github.com/elan-ev/opencast-obs-plugin/blob/master/docs/building.md#building-on-linux section to prevent others from whining around like I had to:Install all necessary building and development libraries viz.
