[cmake-developers] Fragile OS X version checks failing against 10.10

[Sean McBride]

Hi all,

Dunno why I didn't notice until now, but CMake seems to be doing some fragile checks for OS X version numbers.  Specifically in cmCPackPackageMakerGenerator, at least 2 things:

1) a 'double' variable:
  this->PackageCompatibilityVersion = 10.4;

10.10 will compare like 10.1 there.


2) a regex:

    if(OSX_VERSION MATCHES "^10\\.[0123]" OR OSX_VERSION MATCHES "ProductVersion:\t10\\.[0123]")
      message(STATUS "Forcing CTEST_TEST_CPACK=OFF on OSX < 10.4")

Cheers,

--
