Since we are using Meson 0.60.0 or later, use CMake to help us find ICU,
which is cleaner and more comprehensive, and allows us to use libicu_dep
= depedency(...) even on Visual Studio, where CMake will find the
appropriate ICU headers and libraries for us internally.
Sadly, due to peculiarities, we have to live with the warning that comes
up as we needed to look for ICU in the older method instead of the
recommended modules: ['ICU::uc'] method.
In commit aa4909766c an option was
modified and changed its type from a list of possible strings to a
true/false value.
However, the build wasn't updated to correspond to that change, so it
didn't logically work -- and Meson even threw a type error saying you
cannot compare strings to booleans.
The actual change was basically "do not use this option anymore except
to pass a macro to the source file and embed the data at all". So we can
simply get rid of a bunch of complex dependency conditionals.
Fixes#185
Since commit deabd4a, psl2c has been replaced by psl-make-dafsa.
The builtin PSL data is always generated the same way, and the value of the builtin
configure option does not matter anymore.
The built-in data is now embedded by default (instead of the previous "auto"), unless
explicitly disabled by --disable-builtin/-Dbuiltin=false.
When not using an run-time runtime IDNA library (--disable-runtime/-Druntime=no), libpsl can
now include the built-in data without any build-time dependency.
Project and library version are now stored in
version.txt and libtool_version_info.txt files respectively.
Both autotools and meson get their versioning information from this files.
Meson additionally automatically transforms library version
from libtool's own format.
Also raise meson version requirement from 0.47 to 0.57 which
is required by these changes.
We must link to ws2_32.lib for all Windows builds, and we need to use
workarounds for alloca() and snprintf() since Visual Studio uses
_alloca() for alloca() and provides snprintf() only on Visual Studio
2015 or later, meaning that we need to use _snprintf() here.
Also fix the parts where we run the Python scripts to generate items,
since those scripts already have shebang lines for Meson to pick up.
libicu is an internal dependency of libpsl, so if an executable
uses libicu directly, linking on libpsl is not enough, it must also
link on libicu.
Closes: #115
