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
