Subject: [PATCH] Hide commit signature information when fetching commit hash
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

If someone configures git to always show a commit’s signing information,
this breaks the definition of GitVersion in revision.h:

```
#ifndef ASSIMP_REVISION_H_INC
#define ASSIMP_REVISION_H_INC

#define GitVersion 0xgpg: Signature faite le Fri 15 Jun 2018 20:39:53 CEST
gpg:                avec la clef RSA 4AEE18F83AFDEB23
gpg: Impossible de vérifier la signature : Pas de clef publique
878b4b2c
#define GitBranch "master"

#endif // ASSIMP_REVISION_H_INC
```

This can be avoided by passing the `--no-show-signature` to the `git
log` command for retrieving the hash.
