| Subject: [PATCH] src/CMakeLists.txt: fix build on uclibc or musl |
| |
| Build of version 1.3.2 with uclibc or musl fails on: |
| |
| [ 58%] Linking C shared library libpaho-mqtt3c.so |
| /home/buildroot/autobuild/instance-1/output-1/host/opt/ext-toolchain/bin/../lib/gcc/arm-buildroot-linux-uclibcgnueabi/5.5.0/../../../../arm-buildroot-linux-uclibcgnueabi/bin/ld: cannot find -lanl |
| collect2: error: ld returned 1 exit status |
| |
| This is due to commit 21ffebcb749fc8bd8578df85550f03f74e571620 which |
| added a link to anl which is not available on uclibc or musl. |
| |
| Fix this by checking if anl is found on the system before using it |
| |
