mediocregopher opened a new issue #4720: Compilation errors in `pulsar-client-cpp`
URL: https://github.com/apache/pulsar/issues/4720
**Describe the bug**
When attempting to compile `pulsar-client-cpp`, I get these compilation errors:
```
[ 7%] Building CXX object lib/CMakeFiles/pulsarStatic.dir/CompressionCodecSnappy.cc.o

```
**To Reproduce**
Steps to reproduce the behavior:
```
git clone https://github.com/apache/pulsar.git
# git checkout v2.4.0 (optional)
cd pulsar/pulsar-client-cpp
cmake .
make
```
As shown, this happens on both the `v2.4.0` tag and `master`
**Expected behavior**
The build successfully finishes.
**Desktop (please complete the following information):**

**Additional context**
I am able to build the library files using the `docker-build.sh` script, but the built files aren't usable on my system because they are not statically compiled, and the versions of libraries they link to are different.
