# - Returns a version string from Git
|
|
#
|
|
# These functions force a re-configure on each git commit so that you can
|
|
# trust the values of the variables in your build system.
|
|
#
|
|
# get_git_head_revision(<refspecvar> <hashvar> [<additional arguments to git describe> ...])
|
|
#
|
|
# Returns the refspec and sha hash of the current head revision
|
|
#
|
|
# git_describe(<var> [<additional arguments to git describe> ...])
|
|
#
|
|
# Returns the results of git describe on the source tree, and adjusting
|
|
# the output so that it tests false if an error occurs.
|
|
#
|
|
# git_get_exact_tag(<var> [<additional arguments to git describe> ...])
|
|
#
|
|
# Returns the results of git describe --exact-match on the source tree,
|
|
# and adjusting the output so that it tests false if there was no exact
|
|
# matching tag.
|
|
#
|
|
# Requires CMake 2.6 or newer (uses the 'function' command)
