No, that won't work.

You want it to be a semi-colon separated list of arguments.  Not space 
separated.

https://cmake.org/cmake/help/v3.6/prop_tgt/LANG_CLANG_TIDY.html#prop_tgt:<LANG>_CLANG_TIDY


In a ctest script it would be done something like this:

set(DASHBOARD_CLANG_TIDAY
     "/path/to/clang-tidy" "-arg1" "-arg2")


Then put this in the cache:
"CMAKE_CXX_CLANG_TIDY:STRING=${DASHBOARD_CLANG_TIDY}"
