How do I tell CMake to link in a static library in the source directory

Question

I have a small project with a Makefile which I m trying to convert to CMake  mostly just to get experience with CMake  For purposes of this example  the project contains a source file  C    though I don t think the language is particularly relevant  and a static library file which I ve copied from elsewhere  Assume for argument s sake that the source code to the library is unavailable  I only have the  a file and the corresponding header   My handmade Makefile contains this build rule   main  main o libbingitup a     g   -o main main o libbingitup a   which works fine  How do I tell CMake to reproduce this  Not literally this exact makefile  of course  but something that includes an equivalent linking command  I ve tried the obvious but naive ways  like  add executable main main cpp libbingitup a    or  add executable main main cpp  target link libraries main libbingitup a    as well as various things with link directories    or add library bingitup STATIC IMPORTED  etc  but nothing so far that results in a successful linkage  What should I be doing     Version details  CMake 2 8 7 on Linux  Kubuntu 12 04  with GCC 4 6 3

If you don t want to include the full path  you can do  add executable main main cpp  target link libraries main bingitup    bingitup is the same name you d give a target if you create the static library in a CMake project   add library bingitup STATIC bingitup cpp    CMake automatically adds the lib to the front and the  a at the end on Linux  and  lib at the end on Windows   If the library is external  you might want to add the path to the library using  link directories  path to libraries

CMake favours passing the full path to link libraries  so assuming libbingitup a is in   CMAKE SOURCE DIR   doing the following should succeed   add executable main main cpp  target link libraries main   CMAKE SOURCE DIR  libbingitup a
