Hi Leo,

The CMake configuration [1] has both shared and static dependencies on
LibCrypto.

The AWS packages (aws-sdk-cpp and dependencies) are currently built as
static libraries. I would like to build both static and shared but could
not find an example or simple method for building both using cmake. Do you
think it would be worthwhile to extend the cmake-build-system to optionally
configure, build, and install static libraries with additional phases? The
gnu-build-system makes it easy to inline a new phase into the package
definition (when the makefile has both 'make' and 'make static' targets)
but with CMake we are forced to duplicate the configure phase, which is 44
lines of code.

Greg
