I had another thought on this.  Usually it is good enough to build all 
of your applications libraries static, and CMake does handle this.  If 
you use the BUILD_SHARED_LIBS variable in your project you can get it to 
build all the libraries as either static or shared based on the value of 
this variable.

For example:

option(BUILD_SHARED_LIBS "Build Shared Libraries" OFF)
add_library(foo foo.c)
add_executable(bar bar.c)
target_link_libraries(bar foo)

IF BUILD_SHARED_LIBS = OFF then you get static foo, if it is ON, then 
you get a shared foo.   The system libraries are another issue... :)
