Build failure (missing dependency wingpanel-2.0)

[waldyrious]

I tried installing this on a Juno system but got an error when running meson build:

$ git clone https://github.com/PlugaruT/wingpanel-indicator-sys-monitor.git
$ cd wingpanel-indicator-sys-monitor;
$ sudo apt install libgtop2-dev libgranite-dev libgtk-3-dev libwingpanel-2.0-dev meson valac
$ meson build --prefix=/usr

The output of the meson build command was:

Maybe the list of dependencies in the README is not complete?

Hi and thanks for reporting this issue. I will try to replicate this on my machine and come back with a solution.

Update: I ended up bumping into a similar issue for another repo. According to this comment from the thread where I reported it:

Homebrew's pkg-config only reports packages installed by Homebrew

For me the solution was to use the distro's pkg-config instead of Homebrew's. I ran brew uninstall pkg-config (I didn't need it anymore, but I guess I could have simply done brew unlink pkg-config if I wanted to just remove it from the path temporarily).

I can now build the project!
