[CMake] "make package" still fails to work for absolute install locations.

[Thomas Arcila]

Hi,

CPack has support for so called "movable" package (movable = prefix  
independant,
unmovable = prefix prepended to install path), but it's hardcoded to  
movable one.

 from Source/CPack/cmCPackGenericGenerator.cxx

bool movable = true;
   if ( movable )
     {
     // Make sure there is no destdir
     cmSystemTools::PutEnv("DESTDIR=");
     }
   else
     {
     std::string destDir = "DESTDIR=";
     destDir += tempInstallDirectory;
     cmSystemTools::PutEnv(destDir.c_str());
     }

It should not be that difficult to add a CPackConfig.cmake entry  
describing this
behavior. For the time being you can try to force movable to false and see  
if it works
(from what I read, it should, but I dont have time to test it).

I will not have time to look deeper into this before (at least) a week, so  
I hope
it'll be sufficient...
