I'm using pkg-config to find and link against the C libraries inside the build.rs, and it seems to have a .statik(true) option to static link each of them, but the moment I try to set it, it complains that it can't find them:

  The file `nix-expr-c.pc` needs to be installed and the PKG_CONFIG_PATH environment variable must contain its parent directory.
  PKG_CONFIG_PATH_FOR_TARGET contains the following:

I'm using pkg-config to find and link against the C libraries inside the build.rs, and it seems to have a .statik(true) option to static link each of them, but the moment I try to set it, it complains that it can't find them even though the lib/pkgconfig path seems to be correctly configured:

  The file `nix-expr-c.pc` needs to be installed and the PKG_CONFIG_PATH environment variable must contain its parent directory.
  PKG_CONFIG_PATH_FOR_TARGET contains the following:
