Unable to find dependencies while building cmake project

Help
1

I’m currently trying to build the xembedsniproxy without having to add the whole plasma workspace.

To do so, I’ve created the following derivation:

{ 
  stdenv, fetchFromGitHub,
  cmake, qt5, xorg
}:

stdenv.mkDerivation rec {
  name = "xembedsniproxy";
  version = "5.17";

  src = (fetchFromGitHub {
    owner = "KDE";
    repo = "plasma-workspace";
    rev = "Plasma/${version}";
    sha256 = "1dmyh2gxrkk3pyma70q142pma3263fmfjaydqfhsdakh7439njb1";
  } + "/xembed-sni-proxy");

  nativeBuildInputs = [ cmake ];
  buildInputs = [
    qt5.qtbase
    xorg.libxcb
  ];
}

Despite I added libxcb to buildInputs I get the following message:

CMake Error at CMakeLists.txt:6 (find_package):
  By not providing "FindXCB.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "XCB", but
  CMake did not find one.

  Could not find a package configuration file provided by "XCB" with any of
  the following names:

    XCBConfig.cmake
    xcb-config.cmake

  Add the installation prefix of "XCB" to CMAKE_PREFIX_PATH or set "XCB_DIR"
  to a directory containing one of the above files.  If "XCB" provides a
  separate development package or SDK, be sure it has been installed.

I’ve tried to put all the xcb stuff I’ve found using nix search, but I still have this issue. Any ideas ?

Maybe our xcb needs an update (https://xcb.freedesktop.org/#news 1.13.1 → 1.14) - try that and try to add xorg.xcbproto as well.

Tried it, didn’t work either

Have you tried updating them as well?

I will try, but I don’t understand why it would be that ? Since we do use Plasma 5.17 and that xembedsniproxy is currently built within the plasma-workspace derivation currently wouldn’t it mean that all dependencies are available in current nixpkgs ?

I’m not that familiar with the plasma ecosystem in Nixpkgs. Sorry. But, it’s interesting that nix-locate (GitHub - nix-community/nix-index: Quickly locate nix packages with specific files [maintainers=@bennofs @figsoda @raitobezarius]) haven’t found any of this .cmake files the build reports as missing in all of Nixpkgs.
