Building the GUI fails if using wxWidgets 2.6. We need to require 2.8 if for BUILD_GUI to be true.

Unfortunately, the FindwxWin macro does not return the CMake version. We'll have to call wx-config ourselves and sort it out. Here's some code from Google code search:

SET(wxWidgets_USE_LIBS base core xrc html xml adv gl net)
FIND_PACKAGE(wxWidgets REQUIRED)

hugin requires wxwidgets 2.7.0 or above

IF (UNIX)
EXEC_PROGRAM(sh ARGS "${wxWidgets_CONFIG_EXECUTABLE} --version" OUTPUT_VARIABLE wxWidgets_VERSION)
STRING(REGEX REPLACE "^([0-9]+\.[0-9]+)\..*" "\1" wxWidgets_VERSION ${wxWidgets_VERSION})
IF(wxWidgets_VERSION STREQUAL "2.5")
SET(wxWidgets_FOUND FALSE)
MESSAGE("wxWidgets 2.5.x not supported")
ENDIF(wxWidgets_VERSION STREQUAL "2.5")
IF(wxWidgets_VERSION STREQUAL "2.6")
SET(wxWidgets_FOUND FALSE)
MESSAGE("wxWidgets 2.6.x not supported")
ENDIF(wxWidgets_VERSION STREQUAL "2.6")
ENDIF (UNIX)

IF(NOT wxWidgets_FOUND)
MESSAGE("wxWidgets was not found, GUI programs (hugin, nona_gui) disabled")
ENDIF(NOT wxWidgets_FOUND)
