The CMake syntax was a bit too new for our toolchain's CMake. The
following patch was backported:
b2497a8d15
Relevant issue:
https://github.com/curl/curl/issues/12920
As soon as the fix lands in the next curl version, we can remove this
patch again. :^)
This removes the shlib hack from the install step, which repackaged the
static library as the shared one. It also has the benefit of making the
port work with the Clang toolchain :^).
Much redundancy is removed from package scripts with this system.
It also supports simple dependency management, uninstalling (through
BSD ports style plist files), cleaning up after itself (with clean,
clean_dist, clean_all commands), etc.
