[CMake] Help with REGEX expression

[Mike Jackson]

I pulled an older version of the CMake book but came up with this just  
as I got your email..

set (MIN_VERS 10.4)

set (str "/MacOSX/Developer/SDKs/MacOSX10.3.9.sdk")
STRING (REGEX REPLACE "(.*MacOSX*)(....)(.*\\.sdk)" "\\2"   SDK  $ 
{str} )
message (STATUS "replace: ${SDK}")

if (SDK GREATER MIN_VERS)
   message (STATUS "SDK (${SDK}) is greater than MIN_VERS ($ 
{MIN_VERS})")
endif (SDK GREATER MIN_VERS)

set (str "/MacOSX/Developer/SDKs/MacOSX10.4u.sdk")
STRING (REGEX REPLACE "(.*MacOSX*)(....)(.*\\.sdk)" "\\2"   SDK  $ 
{str} )
message (STATUS "replace: ${SDK}")
if (SDK GREATER MIN_VERS)
   message (STATUS "SDK (${SDK}) is greater than MIN_VERS ($ 
{MIN_VERS})")
endif (SDK GREATER MIN_VERS)


set (str "/MacOSX/Developer/SDKs/MacOSX10.5.sdk")
STRING (REGEX REPLACE "(.*MacOSX*)(....)(.*\\.sdk)" "\\2"   SDK  $ 
{str} )
message (STATUS "replace: ${SDK}")
if (SDK GREATER MIN_VERS)
   message (STATUS "SDK (${SDK}) is greater than MIN_VERS ($ 
{MIN_VERS})")
endif (SDK GREATER MIN_VERS)
