Undefined reference to a function in another library

Question

I\'m trying to compile an object code with a reference to one lib. This is the code of libexample.c:

#include \"libexample.h\"
#include 
#include

If you are using cmake, make sure you include the libraries using target_link_libraries(). For e.g., timer functions like timer_create() you need "rt" and for pthread you need "pthread" added using target_link_libraries().
