[CMake] Check directory exists

[David Cole]

>From the good old days before IS_DIRECTORY was invented, you can also use a
trailing "/" trick (hack?) with EXISTS to see if a directory exists and is a
directory...

IF(EXISTS "${maybedir}/")
with a trailing "/" will return false if ${maybedir} is a file that exists,
but true if ${maybedir} is a directory that exists...

I use this to parse only directories out of FILE(GLOB file_list "*")
results.

David
