You cannot change CMAKE_CURRENT_SOURCE_DIR

If you want to separate your sources files from generated files
(be it .o or lib or executable)
you'd better use out-of-source build which is well supported by cmake

mkdir /path/to/build_tree
cd /path/to/build_tree
cmake /path/to/source/tree

You must remove CMakeCache.txt and other CMakeFiles/
from your source tree first.

You may change the generation location of EXECUTABLE and LIBRARY
by setting:
EXECUTABLE_OUTPUT_PATH
LIBRARY_OUTPUT_PATH
