> In trying to set up a build using system libraries installed to non-default paths, CMake doesn't consistently search user-specified paths for libraries.
> For instance, FindDoubleConversion.cmake will look only at ${DoubleConversion_ROOT}/libdoubleconversion.so for the shared library, making it impossible to have a directory setup like doubleconversion/lib/*.so + doubleconversion/include. Other Find*.cmake files set PATH_SUFFIXES to also search the lib/ subdirectory; we should do this everywhere.
> Additionally, it seems the various Find*.cmake files set PATH_SUFFIXES inconsistently. Some hardcode their own list, others use CMAKE_LIBRARY_ARCHITECTURE.
