+Subject: [PATCH] Stop forcing static builds
+
+CMakeLists.txt actually has some checks to make sure some configuration
+options are valid in case of static or shared builds, but that's
+completely useless as it then builds statically no matter what the user
+has specified.
+When not hardcoding static, the library can be build with shared libs or
+without, depending on what value the user passes to -DBUILD_SHARED_LIBS
