Laurent Rineau 291b3029bb Fix a bug in CGAL_SCM.cmake when the HEAD is not a branch ... If the current working directory is a checkout of a commit that is not a branch, for example, a commit in the ancestors of a branch, then CGAL CMake scripts gave that CMake error: == CMake setup == fatal: ref HEAD is not a symbolic ref CMake Error at Installation/cmake/modules/CGAL_SCM.cmake:36 (string): string sub-command REGEX, mode REPLACE needs at least 6 arguments total to command. Call Stack (most recent call first): CMakeLists.txt:17 (include) == CMake setup (DONE) == This patch fixes the error. If HEAD is not a branch, then CGAL_GIT_BRANCH is equal to "HEAD".		2013-01-21 17:23:36 +01:00
