# another format, we'll do the modification before the download so the
# downloaded file has our desired format.

# 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.

# 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:
# https://libgit2.org/docs/guides/build-and-link
# On macOS system, `libgit2' complains about not finding `_iconv*'
# functions! But apparently `libgit2' has its own implementation of libiconv
# that it uses if it can't find libiconv on macOS. So, to fix this problem
# it is necessary to use the option `-DUSE_ICONV=OFF` in the configure step.

# `imfit' doesn't use the traditional `configure' and `make' to install

# installation is manually done by decompressing the tarball, and running
# `scons' with the necessary flags. Despite of that, it is necessary to
# replace the default searching paths in this script by our installation
# paths. This is done with `sed', replacing each ocurrence of `/usr/local'
# by `$(idir)'. After that, each compiled program (`imfit', `imfit-mcmc'
# and `makeimage') is copied into the installation directory and an `rpath'
