Summary:                    CMake docs: suggestion for impovement in OpenMP
section
Description: 
The CMake FindOpenMP docs say that "If the compiler supports OpenMP, the flags
required to compile with openmp support are set." This might be misleading as
these flags are not set for any targets, but instead some variables with these
flags inside are made available to the user.

Furthermore, it might be worth to mention how to use these variables, e.g.:

if (OPENMP_FOUND)
  set_target_properties(... PROPERTIES LINK_FLAGS ${OpenMP_CXX_FLAGS})
  set_target_properties(... PROPERTIES COMPILE_FLAGS ${OpenMP_CXX_FLAGS})
endif()

HTH,
Sylwester
