[CMake] How to specify out-of-source build/lib/bin directories

In order to get an own out-of source path to lib or bin directory you can use following variables:
# set destination paths
SET(LIBRARY_OUTPUT_PATH  ${<PORJECT>_BINARY_DIR}/lib CACHE PATH "Single directory for all libraries." )
SET( EXECUTABLE_OUTPUT_PATH ${<PORJECT>_BINARY_DIR}/bin CACHE PATH "Single directory for all executables." )
MARK_AS_ADVANCED( EXECUTABLE_OUTPUT_PATH )
MARK_AS_ADVANCED( LIBRARY_OUTPUT_PATH )

Where <PORJECT> is the name which was set by PROJECT()
 
Hope to help

Greetings

Alexander
