# Comment from GNUInstallDirs.cmake:
# Override this default 'lib' with 'lib64' iff:
# - we are on Linux system but NOT cross-compiling
# - we are NOT on debian
# - we are on a 64 bits system
# reason is: amd64 ABI: http://www.x86-64.org/documentation/abi.pdf
# For Debian with multiarch, use 'lib/${CMAKE_LIBRARY_ARCHITECTURE}' if
# CMAKE_LIBRARY_ARCHITECTURE is set (which contains e.g. "i386-linux-gnu"
if(CMAKE_SYSTEM_NAME MATCHES "^(Linux|kFreeBSD|GNU)$" AND
NOT CMAKE_CROSSCOMPILING)

# Not debian, rely on CMAKE_SIZEOF_VOID_P:
