I'm trying to install awesome 4.0. To install all the dependencies I ran sudo apt-get build-dep awesome. If I run make in my awesome directory there are some libs still missing:$ makeRunning cmake-- git not found.-- asciidoc -> /usr/bin/asciidoc-- xmlto -> /usr/bin/xmlto-- gzip -> /bin/gzip-- ldoc -> /usr/bin/ldoc-- convert -> /usr/bin/convert-- Checking for modules 'glib-2.0;gdk-pixbuf-2.0;cairo;x11;xcb-cursor;xcb-randr;xcb-xtest;xcb-xinerama;xcb-shape;xcb-util>=0.3.8;xcb-keysyms>=0.3.4;xcb-icccm>=0.3.8;xcb-xkb;xkbcommon;xkbcommon-x11;cairo-xcb;libstartup-notification-1.0>=0.10;xproto>=7.0.15;libxdg-basedir>=1.0.0;xcb-xrm'--   No package 'xcb-xrm' foundCMake Error at /usr/share/cmake-3.5/Modules/FindPkgConfig.cmake:367 (message):  A required package was not foundCall Stack (most recent call first):  /usr/share/cmake-3.5/Modules/FindPkgConfig.cmake:532 (_pkg_check_modules_internal)  awesomeConfig.cmake:153 (pkg_check_modules)  CMakeLists.txt:17 (include)I checked which package I have to install to close this gap apt-cache search xcb-xrm but I got no results. Then I checked the dependencies list from awesome, there is only a entry xcb-util-xrm so I was looking for apt-cache search xcb-util-xrm`. I got also no results. How to install the missing library?$ lsb_release -aNo LSB modules are available.Distributor ID: UbuntuDescription:    Ubuntu 16.04.1 LTSRelease:        16.04Codename:       xenial
No package 'xcb-xrm' found
apt;dpkg
As mentioned by steeldriver, the package is not available until 16.10.One option is to built it manually from source (github)A Second option would be to get it from a 3rd party ppasudo add-apt-repository ppa:aguignard/ppasudo apt-get updatesudo apt-get install xcb-util-xrm
