+Subject: [PATCH] src/CMakeLists.txt: fix static build with a zlib and mbedtls
+
+Static build with a zlib-enabled mbedtls fails on:
+
+[100%] Linking C executable example
+/home/buildroot/autobuild/instance-3/output-1/host/opt/ext-toolchain/arm-buildroot-uclinux-uclibcgnueabi/bin/ld.real: /home/buildroot/autobuild/instance-3/output-1/host/arm-buildroot-uclinux-uclibcgnueabi/sysroot/usr/lib/libmbedtls.a(ssl_tls.c.o): in function `mbedtls_ssl_transform_free.part.24':
+ssl_tls.c:(.text+0xbc6): undefined reference to `deflateEnd'
+
+As mbedtls does not provide a pkg-config file, search for zlib and link
+with it if necessary
