Summary

0013383: CMAKE Autodetect defaults to "NMake Makefiles" when "MinGW Makefiles" should be used.

Description

When i try to generate makefiles using the command line and gui program for cmake, the autodetection feature automatically forces the makefile generator to "NMake Makefiles". This behaviour is incorrect because I do not have visual studio installed at all, and it causes cmake to fail in a scenario where this should not happen.

Steps To Reproduce

1) Use a computer that has never had Visual Studio Installed.
2) Installing Visual studio runtimes is also ok.
3) Install Mingw GCC
4) Install gnu make
4) Install CMake ( i used the provided build of cmake-2.8.8-win32-x86.zip )
5) Select any random cmake project that can be built using cmake and mingw.
6) As long as visual studio itself is not installed, get the dependencies for said project.
7) build makefiles ( cmake . )
8) Compile project

Additional Information

For pkg-config, see: the "Glib and PKG-CONFIG" at this page of the vlc wiki:
http://wiki.videolan.org/Win32CompileMSYSNew [^]
The version of mingw gcc I used is tdm-gcc (mingw-w64 based). This is located at:
http://tdm-gcc.tdragon.net/ [^]
For gnu make, I used the latest build using mingw-w64 located at:
http://sourceforge.net/projects/mingw-w64/files/External%20binary%20packages%20%28Win64%20hosted%29/make/ [^]

A temporary solution is to specify the mingw generator each time you run the cmake, however this is extremely cumbersome and most end developers will probably not want to mess with this in any fashion.

cmake . -G "MinGW Makefiles"

as for an more permanent solution, It's possible to fix this by improving the autodetection code ( lines 2181 to 22225 of Source/cmake.cxx ), or provide windows binaries that are made using mingw ( or mingw-w64) that have "CMAKE_BOOT_MINGW" defined.
