[CMake] Why does CMAKE_FIND_FRAMEWORK always default to FIRST ignoring command line definitions?

[Charlie Sharpsteen]

This is observed OS X 10.6.8, XCode 4.2.6 and 10.7.3, XCode 4.3 with CMake
2.8.8. Say I have the following CMakeLists.txt:

    PROJECT(find_tst)
    CMAKE_MINIMUM_REQUIRED(VERSION 2.8.8)

    MESSAGE(STATUS "Value of CMAKE_FIND_FRAMEWORK: ${CMAKE_FIND_FRAMEWORK}")


Why does CMAKE_FIND_FRAMEWORK end up with a value of FIRST even though I
pass -DCMAKE_FIND_FRAMEWORK=LAST when configuring?

grendel:build sharpie$ cmake .. -DCMAKE_FIND_FRAMEWORK=LAST

Thanks for any insight.
