I don't understand why libGLEW.so.1.10 and libGLEW.so.1.11 are required at the same time

I didn't work during the last two months on one of my projects, today I've compiled it and I tried to run it, but when I try to run it I got this error :

./a.out: error while loading shared libraries: libGLEW.so.1.10: cannot open shared object file: No such file or directory

so I did ldd a.out | grep "GLEW" and got :

libGLEW.so.1.11 => /usr/lib/libGLEW.so.1.11 (0xb7380000)
libGLEW.so.1.10 => not found

locate libGLEW returns :

/usr/lib/libGLEW.so
/usr/lib/libGLEW.so.1.11
/usr/lib/libGLEW.so.1.11.0
/usr/lib/libGLEWmx.so
/usr/lib/libGLEWmx.so.1.11
/usr/lib/libGLEWmx.so.1.11.0

I don't understand why and how my project can link 1.11 and 1.10 at the same time, I check my CMakeLists.txt nothing specify to use 1.10 or 1.11, so from where can come from my problem ? If you need more information I can add some, but right now, I don't know what kind of informations can be usefull to fix this issue. I guess the problem appeared after an update of my OS (archlinux)

To the loader, these are all just file names. It has no concept of versioning.

My guess is that the situation arose because 1.11 is a thin layer perhaps to patch a bug or enhance functionality and is suppose to mostly use the 1.10 version.
