[Ctk-developers] Superbuild issue git_EXEC vs GIT_EXEC

[Daniel Haehn]

Hi guys,

SuperBuild did not work for me this morning:

-- Could NOT find Git  (missing:  GIT_EXECUTABLE)
CMake Error at /opt/local/share/cmake-2.8/Modules/ExternalProject.cmake:825 (message):
  error: could not find git for clone of Log4Qt
Call Stack (most recent call first):
  /opt/local/share/cmake-2.8/Modules/ExternalProject.cmake:1165 (_ep_add_download_command)
  CMakeExternals/Log4Qt.cmake:22 (ExternalProject_Add)
  SuperBuild.cmake:131 (INCLUDE)
  CMakeLists.txt:509 (INCLUDE)

I had to add 

SET(GIT_EXECUTABLE ${git_EXECUTABLE}

to my local Slicer4-Superbuild/CTK/CMakeExternals/Log4Qt.cmake. Then it all works.

Seems just some uppercase/lowercase CMake variable issue.
