Patch by Andreas Enge to force installation of libraries into lib
independently of the architecture, instead of lib32 or lib64.
On x86_64, the C library path coded in CMAKE_C_IMPLICIT_LINK_DIRECTORIES 
contains a library (jack) installed into lib64, which forces lib64
for avidemux with the original code.
