cmake的问题

我的CMakeLists.txt:
cmake_minimum_required(VERSION 3.4)
set(CMAKE_C_COMPILER "gcc")
set(CMAKE_CXX_COMPILER "g++")
set(CMAKE_MAKE_PROGRAM"mingw32-make")
project(fraction)
add_executable(fraction fraction2,cxx)
结果为什么是这样：
S C:\Users\lenovouser\Desktop\cpp\Lesson17\fraction> cmake . -G"MinGW Makefiles"
-- The C compiler identification is GNU 8.1.0
-- The CXX compiler identification is GNU 8.1.0
-- Check for working C compiler: D:/MinGW/mingw64/bin/gcc.exe
CMake Error: Generator: execution of make failed. Make command was: "" "cmTC_f2b2f/fast"
-- Check for working C compiler: D:/MinGW/mingw64/bin/gcc.exe -- broken
CMake Error at D:/cmake/share/cmake-3.8/Modules/CMakeTestCCompiler.cmake:51 (message):
The C compiler "D:/MinGW/mingw64/bin/gcc.exe" is not able to compile a
simple test program.

It fails with the following output:

   Change Dir: C:/Users/lenovouser/Desktop/cpp/Lesson17/fraction/CMakeFiles/CMakeTmp



Run Build Command:"" "cmTC_f2b2f/fast"



Generator: execution of make failed.Make command was: ""

CMake will not be able to correctly generate this project.

我原来用的最新版的cmake也报错，我以为是版本太新了

这个已经解决了，是路径的问题
