[CMake] Fwd: GLOB_RECURSE

Wed Jul 25 22:48:16 EDT 2018

Latest CMake documentation can be found here:

https://cmake.org/cmake/help/latest/

Searching for GLOB_RECURSE there leads to this page:

https://cmake.org/cmake/help/latest/command/file.html

Which is the command you are using. Docs for the command and option you are
using are here:

https://cmake.org/cmake/help/latest/command/file.html?highlight=glob_recurse#glob-recurse

As for your issue, you are misunderstanding the purpose of RELATIVE. That
means the paths you get path will be relative to that path, not that it
searches from that path. So you are just searching for “*.cpp” and “*.c” in
the CURRENT directory. That is why you are getting files in all the
subdirs. As @frodak pointed out in his first example, you need to remove
the RELATIVE and put the dir name you want like “./dir/*.cpp”.

Once you do that, you should be good to go. All of the above is explained
pretty clearly in the linked docs.
