Because we prepended libraries to list, CMake had troubles resolving
link directory order as it detected some cycles. Appending to list ensures
that dependencies will preceed dependees.
One header at a time is the right way. Apart from that the output on
windows goes from:
...

CMake 2.6 is already a bit old. Many bugs have been fixed since
its release. We use 2.8 in our company and we have no intention
of polluting our environment with old software, so 2.6 would
not be tested. This shouldn't be a problem since all one need
to build CMake from source is C and C++ compiler.
All C and H files now (should) feature the proper project curl source
code header, which includes basic info, a copyright statement and some
basic disclaimers.
The CheckTypeSize module that comes with CMake 2.6.2 and above does
everything we need and also supports cross-compiling. Avoid duplicating
an older version of it here. This also fixes a cross-compiling error
because the old line
include ("${CMAKE_MODULE_PATH}/CheckTypeSize.cmake")
failed because CMAKE_MODULE_PATH is a search path and not a directory.
