CMake determines the Icinga 2 version number using `git describe` if the
source directory is contained in a Git repository. Otherwise the version number

+is extracted from the [VERSION](VERSION) file. This behavior can be
overridden by creating a file called `icinga-version.h.force` in the source
directory. Alternatively the `-DICINGA2_GIT_VERSION_INFO=OFF` option for CMake
can be used to disable the usage of `git describe`.
Copy the icinga2.spec file to `rpmbuild/SPEC` or fetch the latest version:
```
-curl https://raw.githubusercontent.com/Icinga/icinga2/master/icinga2.spec -o $HOME/rpmbuild/SPECS/icinga2.spec
+curl https://raw.githubusercontent.com/Icinga/rpm-icinga2/master/icinga2.spec -o $HOME/rpmbuild/SPECS/icinga2.spec
```
Copy the tarball to `rpmbuild/SOURCES` e.g. by using the `spectool` binary
