Subject: [PATCH] BUG: VERSION_LESS_EQUAL introduced in cmake 3.7

Older versions of cmake, according to documentation:
https://cmake.org/cmake/help/v3.5/command/if.html , do not know
VERSION_LESS_EQUAL, just VERSION_LESS.

This leads to errors:

CMake Error at somewhere/jsoncpp/CMakeLists.txt:18 (if):
  if given arguments:

    "3.5.1" "VERSION_LESS_EQUAL" "3.13.1"

  Unknown arguments specified

Resolves: #866
