membuat masalah di Windows

Saya mencoba mengkompilasi potongan kode ini (cukup rumit) dengan cmake dan MinGW di Windows:

#include <iostream>

int main()
{
    std::cout << "Test" << std::endl;
    return 0;
}

Ini adalah file CMakeLists.txt (yang berfungsi dengan benar di Linux):

cmake_minimum_required(VERSION 2.6)

SET(CMAKE_C_COMPILER path/to/gcc)
SET(CMAKE_CXX_COMPILER path/to/g++)

project(cmake_test)

add_executable(a.exe test.cpp)

Dengan perintah:

cmake -G"MinGW Makefiles" .

Saya mendapatkan kesalahan ini:

CMake Error at C:/Program Files (x86)/CMake 2.8/share/cmake-2.8/Modules/CMakeMinGWFindMake.cmake:20 (MESSAGE):
  sh.exe was found in your PATH, here:

  C:/MinGW/msys/1.0/bin/sh.exe

  For MinGW make to work correctly sh.exe must NOT be in your path.

  Run cmake from a shell that does not have sh.exe in your PATH.

  If you want to use a UNIX shell, then use MSYS Makefiles.

CMake Error: Error required internal CMake variable not set, cmake may be not be built correctly.
Missing variable is:
CMAKE_C_COMPILER_ENV_VAR
CMake Error: Could not find cmake module file:C:/cmake_test/CMakeFiles/CMakeCCompiler.cmake
CMake Error: Error required internal CMake variable not set, cmake may be not be built correctly.
Missing variable is:

-- Configuring incomplete, errors occurred!

Kesalahan ini tidak banyak membantu saya. Mengingat ini berfungsi di Linux, itu pasti ada hubungannya dengan konfigurasi Window.

Terima kasih atas bantuannya!

Konfigurasi:
- Windows 7
- MinGW/GCC 4.6.1
