I found several CMake-built libraries on x86_64 (graphite2, openjpeg,
qjson) that all use lib/, not lib64/.
Then I found one counterexample, libftdi; however, setting
CMAKE_INSTALL_LIBDIR=lib doesn’t make any different: it still installs
libraries in $out/lib64. Any idea?
Here’s the patch I tried:

According to <http://www.cmake.org/Wiki/CMake_Useful_Variables>,
LIBRARY_OUTPUT_PATH might be better for this, no?

You’re talking about .cmake files, right?
Could you try the attached patch and report back?
