Yes, that is bad practice IMO. FIND_PATH() should look just for the file in 
some default locations it is known to be on many platforms (including 
registry settings on Windows if there are install packages that installs and 
registers locations) but should not assume there is always the "curl" 
directory. Because of that bad FIND_PATH() not even setting (according to the 
documentation) the following variables before calling on FIND_PACAKGE() 
helps:
                 CMAKE_FRAMEWORK_PATH
                 CMAKE_APPBUNDLE_PATH
                 CMAKE_INCLUDE_PATH

AFAIK that is the standard procedure to have your project specify additional 
lookup paths for includes and libraries without having to modify the original 
Find package code.
