[CMake] libdir question

[Frans de Boer]

Dear Readers,

I guess that my question has been asked many time before, but I could 
not find it. So her it is (again): Using './configure --libdir=...' one 
can set the base directory where the libraries are supposed to be 
placed. CMake has so many options, which also need to be modified in the 
CMakeLists.txt file that it is bewildering. Can anybody help me how I 
can specify a different library directory - lib64 - instead of the 
standard 'lib'. I want to keep my system clean without the /usr/lib 
directory being cluttered with 64-bit libraries.

Regards, Frans.
