Attempt to build in-source detected.

Please do the following:
1. Remove the in-source generated files:
    rm -rf CMakeFiles CMakeCache.txt
2. Build out-of-source as follows:
    mkdir build (or whatever you want to call your build directory)
    cd build && cmake ..
Now you can execute make as many times as you want, without the need to re-execute cmake.")
