+Subject: [PATCH] src/CMakeLists.txt: do not force the build of a shared
+ library
+
+By definition, projects using CMake which can build either static or shared
+libraries use a BUILD_SHARED_LIBS flag to allow selecting between both.
+So, let CMake rely on the standard BUILD_SHARED_LIBS variable to decide
+whether a static or shared library should be built.
+
+however, we can control the behaviour as follows:
+
+   $. cmake -DBUILD_SHARED_LIBS=OFF ...
+
+   $. cmake -DBUILS_SHARED_LIBS=ON ...
+
+With Yocto/OE, just add the following option into the libubootenv recipe :
+
+EXTRA_OECMAKE = "-DCMAKE_BUILD_TYPE=Release -DBUILD_SHARED_LIBS=ON"
