Hi Karl, You could do so something like that:
set(bitness 32) if(CMAKE_SIZEOF_VOID_P EQUAL 8) set(bitness 64) endif() The following macro provides a more complete example... http://viewvc.slicer.org/viewvc.cgi/Slicer4/trunk/CMake/SlicerMacroGetPlatformArchitectureBitness.cmake?view=markup # # SlicerMacroGetPlatformArchitectureBitness(<var-prefix>) # is used to extract information associated with the current platform. # # The macro defines the following variables: # <var-prefix>_BITNESS - bitness of the platform: 32 or 64 # <var-prefix>_PLATFORM - which is on the this value: linux, macosx, win # <var-prefix>_ARCHITECTURE - which is on the this value: i386, amd64, ppc Hth Jc On Wed, Jun 22, 2011 at 7:33 PM, Karl Merkley <k...@elemtech.com> wrote: > > I need to install a library into a directory whose name depends on the > machine type.
