1) Explicitly pass -DCURL_INCLUDE_DIR=/usr/local/include to cmake.
2) Point -DCMAKE_INCLUDE_PATH command line parameter or environment variable 
to /usr/local/include. This forces cmake to search in /usr/local/include 
first.
3) make 2-step find_path call (from cmake --help-command find_path)

Therefore, you first specify /usr/local/include in PATHS (as you done it) and 
set NO_DEFAULT_PATH. And make second call to use usual search order.
