Why doesn't CMake find Boost? - cmake

Question

i try to use Boost unit test framework to test my static library but CMake cannot find Boost in spite of BOOST_ROOT, CMAKE_INCLUDE_PATH, CMAKE_LIBRARY_PATH are set before call to find_package. Actually i've tried a lot of options based on the answers to similar question but still without any success.
cmake version:3.6.1
boost version:1.60.0
Here is link to my project on GitHub
And here is log output from TravisCI
CMakeLists.txt:
