[Bro-Dev] Building bro 2.6 with static broker/caf libraries

[Philippe Antoine]

In case it is helpful, here is the script I used to build all static bro (without any shared libraries)

```
cd bro

mkdir buildcaf
cd buildcaf
cmake -DCAF_NO_UNIT_TESTS=1 -DCAF_NO_EXAMPLES=1 -DCAF_BUILD_STATIC_ONLY=1 ../aux/broker/3rdparty/caf/
make
make install || true
cd ..

mkdir build
cd build
cmake -DDISABLE_PYTHON_BINDINGS=1 -DENABLE_STATIC_ONLY=1 -DCAF_ROOT_DIR=../buildcaf ..
make
make install
```

It needed also a small patch to bro, which comes afterwards
```
diff --git a/CMakeLists.txt b/CMakeLists.txt

```
