I'm trying to create a derivation using nix files, and I'm a little stuck. A package I'm trying to install has a sh file in its repo to build it, and this sh file is running CMake with some arguments.

More specifically, this package is vcpkg.

Here's my vcpkg.nix file:

{ gcc11Stdenv, fetchFromGitHub, ninja, cmake, bash }:

gcc11Stdenv.mkDerivation {
  name = "vcpkg-2021.05.12";

  src = fetchFromGitHub {
    owner = "microsoft";
    repo = "vcpkg";
    rev = "2021.05.12";
    sha256 = "0290fp9nvmbqpgr33rnchn5ngsq4fdll2psvh0bqf0324w2qpsjw";
  };

  buildPhase = ''
    ./bootstrap-vcpkg.sh -useSystemBinaries
  '';
}

When running it with nix-shell -p 'with (import <nixpkgs> {}); callPackage ./vcpkg.nix {}', I get this error:

Could not find cmake. Please install it (and other dependencies) with:

       For full logs, run 'nix log /nix/store/riq6vjdhv4z3xvzp8g597xjgwf2rvm03-vcpkg-2021.05.12.drv'.

Then, I thought of making cmake and ninja available to buildPhase so the script can use those binaries by adding buildInputs = [cmake ninja];, but I then get this error:

       For full logs, run 'nix log /nix/store/76djky7f3xy6ym6v3qlmy941z0bjb8xw-vcpkg-2021.05.12.drv'.

It seems that adding cmake to buildInputs makes nix try to configure the project using cmake, but this is not what I'm trying to do since vcpkg don't simply have a CMakeLists.txt file in its repo.

Adding inherit cmake ninja; didn't seem to help.

You can prevent cmake from changing the configure phase by setting dontUseCmakeConfigure=true in your derivation.

From the nixpkgs manual:

6.7.29. cmake

Overrides the default configure phase to run the CMake command. By default, we use the Make generator of CMake. In addition, dependencies are added automatically to CMAKE_PREFIX_PATH so that packages are correctly detected by CMake. Some additional flags are passed in to give similar behavior to configure-based packages. You can disable this hook’s behavior by setting configurePhase to a custom value, or by setting dontUseCmakeConfigure. cmakeFlags controls flags passed only to CMake. By default, parallel building is enabled as CMake supports parallel building almost everywhere. When Ninja is also in use, CMake will detect that and use the ninja generator.
