+Subject: [PATCH] CMakeLists.txt: add BUILD_TESTS option
+
+Add an option to enable or disable tests. This will allow the user to
+build c-periphery without threads and will avoid the following build
+failure:
+
+[ 68%] Building C object CMakeFiles/test_serial.dir/tests/test_serial.c.o
+/data/buildroot/buildroot-test/instance-0/output/build/c-periphery-2.2.1/tests/test_gpio_sysfs.c:13:10: fatal error: pthread.h: No such file or directory
+ #include <pthread.h>
