# Libraries
# ---------
#
# We would prefer to build static libraries, but some compilers like LLVM
# don't have static capabilities, so they'll only build dynamic/shared
# libraries. Therefore, we can't use the easy `.a' suffix for static
# libraries as targets and there are different conventions for shared
# library names.
#
# For the actual build, the same compiler that built the library will build
# the programs, so exact knowledge of the suffix is ultimately irrelevant
# for us here. So, we'll make an `$(ildir)/built' directory and make a
# simple plain text file in it with the basic library name (an no prefix)
# and create/write into it when the library is successfully built.

# Libraries with special attention on Mac OS
# ------------------------------------------
#
# Libgit2 and WCSLIB don't set their installation path, or don't do it
# properly, in their finally installed shared libraries. But since we are
# linking everything (including OpenSSL and its dependencies) dynamically,
# we need to also make a shared libraries and can't use static
# libraries. So for Mac OS systems we have to correct their addresses
# manually.
#
# For example, Libgit2 page recommends doing a static build, especially for
# Mac systems (with `-DBUILD_SHARED_LIBS=OFF'): "It’s highly recommended
# that you build libgit2 as a static library for Xcode projects. This
# simplifies distribution significantly, as the resolution of dynamic
# libraries at runtime can be extremely problematic.". This is a major
# problem we have been having so far with Mac systems:
