#### Install all dependencies:
```shell
-brew install cmake openssl protobuf boost boost-python3 googletest zstd snappy
+brew install cmake openssl protobuf boost googletest zstd snappy
```
#### Compile Pulsar client library:
```shell
-cmake .
+cmake . -DCMAKE_CXX_STANDARD=14
+make
+```
+
+You need to configure `CMAKE_CXX_STANDARD` with 14 because the latest `googletest` dependency from HomeBrew requires the C++14 support. If you don't want to build tests, you can run:
+
+```bash
+cmake . -DBUILD_TESTS=OFF
make
```
If you want to build performance tools, you need to run:
```shell
-cmake . -DBUILD_PERF_TOOLS=ON
+cmake . -DBUILD_PERF_TOOLS=ON -DCMAKE_CXX_STANDARD=14
make
```
