every single tutorial I have found online does not work on manjaro at least not for me.
on the github page of obs-v4l2sink the instructions are:
git clone https://github.com/CatxFish/obs-v4l2sink.git
cd obs-v4l2sink
mkdir build && cd build
cmake -DLIBOBS_INCLUDE_DIR="../../obs-studio/libobs" -DCMAKE_INSTALL_PREFIX=/usr ..
make -j4
sudo make install
When I try this,
it tells me when i get to the cmake -DLIBOBS_INCLUDE_DIR="../../obs-studio/libobs" -DCMAKE_INSTALL_PREFIX=/usr ..
part it gives me this error message:

I have not tried to compile and install the v4l2Loopback since I have not been able to make the v4l2sink.
can anyone teach me how to do this right from the getgo and if I run into a similar situation further-on in my arch/Manjaro career I don’t need help to resolve it?
So what you are saying I need to install the base-devel package first, and then the pacman gui will be able to build it?
or
If I install the base-devel package the steps on the Github page will work?
I’ve been trying to find a tutorial on how to do it myself manually but I have had no luck. do you know of a good tutorial on it and could point me in the right direction? I’ve been searching on archwiki but I can’t seem to find what I’m looking for.
the book Linux for dummies did not help on the matter either.
I did not know that DE did not matter, but no I know. so I will not put that tag in any other posts. thank you.
@megavolt thank you for your answer. I’m going to look further in to it.
but after installing pacman -S base-devel I could build it with the add and remove gui. I’m going to read your links and try to build it myself too.
if you had to describe what a linux-headers is, really simplified to a newbie, I would much appreciate it. as some descriptions get way over my head. lol
If you compile code, does mean: translate a programming language into machine code, then there are code libraries which are shared with other code, so that it can be reused. This code are so called header-files, which can be included with a simple line in any code to ensure all code parts use the same bases and work with each other.
If you use DKMS (Dynamic Kernel Module Support), then the module (driver) gets compiled against the current kernel and therefore it includes the header files of the current kernel. Without the header files it can not be compiled, since code is missing. On every new kernel version it must be re-compiled.
