Yes. CMake removes the RPATH from the executables, because it uses the
RPATH to allow program execution dependant on compiled libraries
without needing installtion. That can be omitted with
-DCMAKE_BUILD_RPATH=OFF.


Thanks to Marc Weber, I decided for a way of development. I use a
config.nix with things like these:
{
  packageOverrides = pkgs : with pkgs; rec {

      dwmEnv = pkgs.myEnvFun {
          name = "dwm";
          buildInputs = [ stdenv xlibs.libX11 xlibs.libXinerama ];
      };
  };
}

Then, after installing "env-dwm" into my profile, I load the build
environment with a script named "loadenv", as with "loadenv dwm":
---------
#!/bin/sh

OLDPATH="$PATH"
source $HOME/.nix-profile/dev-envs/$1
PATH="$PATH:$OLDPATH"
export PS1="\n$1:[\u@\h:\w]\$ "
export buildInputs
export NIX_STRIP_DEBUG=0

bash --norc

---------
This gives me the 'env' loaded in the prompt, and I can exit it
exiting the new bash. I also have all the PATH I had before the
'source' command.

Regards,
Lluís.
