[CMake] [Windows][msvc-9.0] Wired bug if MATLAB's gmake is on the path

[Maik Beckmann]

Hello fellow cmakers,

I've encountered a weired bug:  Given that CMake is installed in 
  C:/Programme/CMake
and MATLAB's bin folder is on the path before cygwin's, cmake fails on

{{{
cmake_minimum_required(VERSION 2.6)
project(Foo C)
}}}

with

{{{
mkdir Debug
cd Debug && cmake -G"Unix Makefiles" -DCMAKE_BUILD_TYPE=Debug ../

  It fails with the following output:

It fixed by either:
  1. Let CMake use cygwin's make:
    - In cygwin's bin folder copy make.exe to gmake.exe and place it at the 
beginning of PATH
    - Setting CMAKE_MAKE_PROGRAM to cygwin's make

  2. Let CMake use MATLAB's gmake, but 
   - The install location has an space in it (like C:/Programme/CMake 2.6/)
   - The environment variable MAKE is set to "make" (set MAKE=make)

While the 1. solutions reasonable to me, I have no idea why 2. fixes the 
problem as well.  Its just weired.

I observed that in case it works 
  CMakeFiles/CMakeCCompiler.cmake
is there, but missing for the failing one.


What bugs me most is the inconsistency for the failings.  Why doesn't it work 
if the installation path has a space in it...  Hints Anyone?

Best,
