Summary:                    Raspbian puts some system libraries in
/usr/lib/arm-linux-gnueabihf which CMake doesn't search
Description: 
Raspbian, which is a streamlined offshoot of Debian for Raspberry Pi, puts a lot
of system libraries in /usr/lib/arm-linux-gnueabihf, which CMake doesn't search
for by default.

Some popular libraries include libpng, libjpeg, libcurl, openal, sdl, avahi,
freetype, and a lot more.

When trying to build on a Raspberry Pi (not cross-compiling), CMake couldn't
find and link a lot of  common libraries.

Since Raspbian is essentially just another Linux distro and probably shouldn't
be an entirely different platform, 
the easiest fix seems to be to add 
/usr/lib/arm-linux-gnueabihf
to
CMAKE_SYSTEM_LIBRARY_PATH
CMAKE_PLATFORM_IMPLICIT_LINK_DIRECTORIES
in Modules/Platform/UnixPaths.cmake


Steps to Reproduce: 
I think I originally triggered this by trying to FIND_PACKAGE(OpenAL) on
Raspbian.
