Isn't it missing 3rdparty/libconfig/CMakeLists.txt file?
Cause I get
CMake Error at 3rdparty/CMakeLists.txt:51 (add_subdirectory):
The source directory
/cygdrive/x/SERVER/RATHENA/svn/trunk/3rdparty/libconfig
does not contain a CMakeLists.txt file.
I don't care if anybody's server has enough population or not. There are always successful servers and less successful. From rAthena's standpoint it doesn't matter which one is which.
