Summary0004222: ADD_LIBRARY should support simultaneous STATIC | SHARED builds
DescriptionCurrently, CMake defaults to have ADD_LIBRARY support either a static or a shared library build.
Unfortunately, these statements/switches are exclusive from each other.

This is somewhat wrong and more limiting than autoconf. ADD_LIBRARY() should support creating both static and shared built libraries, so that the result (on Unix, for example, is):

libZZZ.so
libZZZ.a

Currently, cmake forces you to create two builds for obtaining a similar behavior (and it is problematic for large projects that may need to mix some libraries being created static, some both and some shared).

I would like to see this, too. But when this goes in we need a way to specify to which version another target links.

For those interested this can be worked around with some CMake wrapping macros.

We use a global variable that includes either STATIC, SHARED, or both in a list, and then wrap ADD_EXECUTABLE and ADD_LIBRARY to create targets with "-shared" and "-static" suffixes. Then we wrap TARGET_LINK_LIBRARIES for our own libraries to do the same. The net effect is with a few macros you can create both shared and static simultaneously.

CMake might also need to either provide a way to generate multiple IMPORTED targets on export(), or generate IMPORTED targets with multiple LOCATION_FOO properties.
