description     2Geom is a computational geometry library intended for use with \
                2D vector graphics.
long_description \
                ${description} It concentrates on high-level algorithms, such as \
                computing the length of a curve or Boolean operations on paths.

# Xcode Clang 10.x is based on LLVM 6.x. And it does not include an upstream fix, for the
# following (valid) scenario involving templates:
#
#   MyTemplate(some_arg);
#
# It can be sidestepped, by explicitly declaring a variable of that template type:
#
#   MyTemplate myVar(some_arg);
#
# But since this is an LLVM 6.x bug - and one that was ultimately fixed, after Xcode 10.x was
# released - it arguably shouldn't be necessary.
#
# The specific compilation error for this scenario is:
#   error: cannot use parentheses when declaring variable with deduced class template specialization type
#
# See: https://trac.macports.org/ticket/68036
