i.e., Debian systems need the following dev packages:

Compiling Neutralinojs...
Package gtk+-3.0 was not found in the pkg-config search path.
Perhaps you should add the directory containing `gtk+-3.0.pc'
to the PKG_CONFIG_PATH environment variable
No package 'gtk+-3.0' found
Package webkit2gtk-4.0 was not found in the pkg-config search path.
Perhaps you should add the directory containing `webkit2gtk-4.0.pc'
to the PKG_CONFIG_PATH environment variable
No package 'webkit2gtk-4.0' found
Package glib-2.0 was not found in the pkg-config search path.
Perhaps you should add the directory containing `glib-2.0.pc'
to the PKG_CONFIG_PATH environment variable
No package 'glib-2.0' found
Package xrandr was not found in the pkg-config search path.
Perhaps you should add the directory containing `xrandr.pc'
to the PKG_CONFIG_PATH environment variable
No package 'xrandr' found

Found:

Debian: libgtk-3-dev libwebkit2gtk-4.0-37 libwebkit2gtk-4.0-dev libglib2.0-dev libxrandr-dev
