* xenial doesn't ship many dependencies, so make them all optional
since we don't guarantee that everything will work
* cmake/{5,6}: needs stdlib.h for EXIT_SUCCESS on GCC 5
* common/222: needs C++11, and GCC 5 doesn't understand `auto`
correctly unless we explicitly enable it.
* frameworks/1 boost: xenial doesn't ship boost_python3, so make it
properly optional
* frameworks/6 gettext: gettext can be installed without xgettext,
which doesn't cause the project to fail, but the installed files
list is different which causes the test to fail.
* frameworks/7 gnome: gobject-introspection can't be enabled because
the sanitizer unit test detects leaks in glib and fails
cmake: get language from Meson project if not specified as depedency(..., langugage: ...)
deps: add threads method:cmake
dependency('threads', method: 'cmake') is useful for cmake unit tests
or those who just want to find threads using cmake.
cmake: project(... Fortran) generally also requires C language
This adds a new method, partial_dependency to all dependencies. These
sub dependencies are copies of the original dependency, but with one or
more of the attributes replaced with an empty list. This allows creating
a sub dependency that has only cflags or drops link_arguments, for
example.
With the headers from cygwin-devel-2.10.0-1, getpagesize() is not prototyped
unless an appropriate feature test macro is defined.
Future work: investigate if this needs to be defined by
BoostDependency.get_compile_args() or in Boost.
Also, use '^' to escape newlines in appveyor-install.bat to avoid an
absurdly long line, remove some unnecessary quotation, and alphabetically
sort packages
Also, define the _XOPEN_SOURCE feature test macro in the boost test to avoid
'not declared in this scope' warnings for pthread_rwlock_init(), etc.
The new implementation will correctly pick boost from 3 possible
locations on windows and two locations on posix compatible OSs.
The new search algorithm also differentiates between debug and
release builds of Boost and multi or single threading builds.
It was also decided to map "Meson modules" to Boost software libraries
and not Boost modules since it there are a lot of options regarding
linking. Some modules can even be used either as headers-only or with
dynamic linking.
This commit also fixes a bug that prevented header-only use on Windows.
