Compilando Polybar no Devuan (Debian)

Dica testada no Devuan Ascii (Debian Stretch).

Ao tentar compilar o Polybar, me deparava com o erro:

--   No package 'xcb-composite' found
CMake Error at /usr/share/cmake-3.7/Modules/FindPkgConfig.cmake:415 (message):

Faltando "xcb-composite"? Mas ele estava instalado pelo pacote "libxcb-composite0"! Então descobri que era o pacote "libxcb-composite0-dev" que deveria ser instalado.

Então, em resumo, a compilação do Polybar ficou assim:

Instalação de dependências:

# apt-get install cmake cmake-data libcairo2-dev libxcb1-dev libxcb-ewmh-dev libxcb-icccm4-dev libxcb-image0-dev libxcb-randr0-dev libxcb-util0-dev libxcb-xkb-dev pkg-config python-xcbgen xcb-proto libxcb-xrm-dev i3-wm libasound2-dev libmpdclient-dev libiw-dev libcurl4-openssl-dev libpulse-dev libxcb-composite0-dev

Clone:

git clone https://github.com/jaagr/polybar.git

E build:

cd polybar && ./build.sh

É isso.
