Allow ldc to be a submodule. This uses changes from
https://github.com/rpavlik/cmake-modules.
(cherry picked from commit 0be5ead42e6049f8e51453a82a17b1770646a1a2)
FindGit doesn't seem to work as expected on Ubuntu 10.04
(GIT-NOTFOUND even though Git is installed and available
on the $PATH).
This implementation might be overly simplistic and it
should probably use find_program() to locate Git. We need
to revisit this after the 0.12.0 release is out.
This allows for building of release packages without
manually overriding the version string.
The --tag argument is needed to pick up un-annotated tags
as well.
CMakeLists.txt contains now the version numbers for DMD and (next) LDC release.
If a .git folder is found then the LDC version is replaced by the first 6 chars
of the Git revision.
Possible improvements:
- If the build is not done at the master branch then it could be useful to check for a tag and use the tag instead of the revision. (for release builds)
- Maybe it is useful to include the branch name.
This fixes issue #366.
