Since this is only consulted while constructing the Dependency object, it's
result doesn't depend on the instance (and it would make no sense if it did)
Special case ThreadDependency by taking compiler's flags and
PkgConfigDependency by adding them in requires(.private) instead. For
other Dependency objects just take their link_args and compile_args.
Closes#2725
The sysconfig config variables are different on MSYS2 and the paths
are also different. We now also use the full path to the import or
static library instead of using -Lfoo -lpython35 etc.
Also obey the value of the 'static' keyword argument.
sysconfig.get_platform() returns 'mingw' with MSYS2, so we need to
use some other method; in this case I chose to use the CC that
Python was compiled with, which is a relatively reliably indicator
unless people start using Python on Windows compiled with Clang or
something.
Also try harder to find a compiler that dependencies can use.
This means that in C++-only projects we will use the C++ compiler for
compiler checks, which can be important.
pkg-config enables to define variables by using the define-variable
option. This allows some packages to redefine relative paths, so
files can be installed in the same relative paths but under prefix.
BOOST_LIBS could become outdated in future versions, which would result
in dependency('boost', modules : [ 'foo' ], required : false) to fail,
although required was set to false. Therefore turn the exception into
log_fail(). If required was set to true, this will still be caught since
is_found remains False.
This also improves logging by printing all invalid module names instead
of only the first one.
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.
Fixes: #2274#2239#1803#669
* add support for cups dependencies
libcups has its own cups-config tool rather than using pkg-config.
This adds support for cups-config, based on pcap-config and
sdl2-config implementations.
This change also includes the unit test case and documentation for
cups dependency object implementation, and libcups2 dep to CI image.
