I'd like to reiterate my request for the attached patch. CMake 2.6.0
has become even more picky about the choice of compiler and now
completely delete the cache during a make rebuild_cache stage.
Step to reproduce:
- debian oldstable (where all package are build gcc 3.3, aliased to c++)
- default c++ executable pointing to g++-4.2
When importing any of the official debian package (build with
configuration CXX=c++, which at the time was aliased to g++-3.3),
there is no way to actually say use g++-3.3 to link against the
imported package. CMake will always force to use 'c++' which is wrong.
Patch is totally non-intrusive.
Thanks
-Mathieu
Ps: of course on debian, c++ can be re-alias to anything you want, but
require root/sudo power.
