compile caffe with cmake got errors!

[mjj...@gmail.com]

Hi , I have tried to compile caffe using cmake, I did as follow:

1. mkdir build

2. cd build

3. cmake ..

and then, I got error like follow:

CMake Error at cmake/Cuda.cmake:112 (string):

  string sub-command COMPARE does not recognize mode GREATER_EQUAL

Call Stack (most recent call first):

  cmake/Cuda.cmake:264 (caffe_select_nvcc_arch_flags)

  cmake/Dependencies.cmake:77 (include)

  CMakeLists.txt:46 (include)

besides,I check the CMakeError.log:

Determining if the pthread_create exist failed with the following output:
