CMake: Determine Version in Chechout with --notags
...otherwise determining a version in case of git fetch --notags && git checkout
will fail with:
cmake ..
-- Git project directory is clean.
-- Building Allpix^2 version fatal: No names found, cannot describe anything..
-- Building "RelWithDebInfo"
CMake Error at CMakeLists.txt:43 (PROJECT):
VERSION "." format invalid.
-- Configuring incomplete, errors occurred!
Now instead CMake reports:
cmake ..
-- Git repository present, but could not find any tags.
-- Building Allpix^2 version v2.0.0-unknown.
-- Building "RelWithDebInfo"
...with the latest project version from the CMakeLists.txt
file.
