D is not a 'c-like' language, but it can link to C libraries. The same
might be true of Rust in the future and Go when we add support for it.
This contains no functionality changes.
All dependencies were using find_library, has_header, get_define, etc on
self.compiler assuming that it's a compiler that outputs and consumes
C-like libraries. This is not true for D (and in the future, for Rust)
since although they can consume C libraries, they do not use the
C ecosystem.
For such purposes, we now have self.clib_compiler. Nothing uses
self.compiler anymore as a result, and it has been removed.
debugoptimized builds building against Qt would ultimately link against
both the debug and non-debug msvcrt, ntdll, etc libraries which causes
crashes in weird places and is very much not recommended by Microsoft.
This changes the selected Qt library(ies) correctly to not uses the
debug variants for debugoptimized builds.

This reverts commit 0045d95a16.
<jeandet> nirbheek, it seems 0045d95a16 is
really wrong, I've tested on Ubuntu. While writing this line I was
thinking that you can't have Qt without a working qmake in the path. On
Ubuntu you have that qtchooser stuff which is misleading.
Currently, ExternalProgram get_path() assumes the last component in the
path is always the actual command path. However, this is not always
right. For example, in the command "python -u", we should return
"python" and not "-u". However, in other cases, like "python script.py",
then the last component is the right one.
The heuristic that seems to capture this is to use the last argument
that is still a file. This means options get ignored, but "python
script.py" still works. Let's use this heuristic, at least for now.
Removed Qt4 private headers test since it's hard to get Qt4 private
headers installed on CI.

This commit adds private_headers option in dependency method which tells
QtDependency to add private headers include path to build flags.
Since there is no easy way to do this with pkg-config only qmake method
supports this, so with private_headers set qmake will always be used.

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.
This halves the configure time in gst-build, the aggregate of all
GStreamer repositories.
We can't do this to Popen_safe because we can't be sure that other
programs have no side-effects and will always return the same output
for the same arguments and environment.
Strawberry Perl on Windows ships with a Perl implementation of
pkg-config embedded inside a BAT file. True horror of horrors, but
people do use it, so search for pkg-config with ExternalProgram which
has the right Windows-specific cases to deal with that.

ExtraFrameworkDependency doesn't support any method: other than auto, so
handing down the method: used from QtBaseDependency leads to (sic):
meson.build:13:2: ERROR: Unsupported detection method: qmake, allowed methods are auto and auto
At the moment, QtBaseDependency._framework_detect sets is_found if at least
one module is found. This gives the incorrect result in the case where both
found and not-found modules are given.
Fix it so it only sets is_found if all the modules given are found.
Fix dependency('qt4|5', method: 'qmake') detection when shared library
extension isn't .so
Note that OSX already has a special case to look for .framework
Unusually, the cygwin package for openmpi installs headers into
/usr/include, rather than /usr/include/openmpi
Prevent pkg-config from suppressing that -I flag, so a gfortran INCLUDE can
find those files
Also don't resolve -lfoo args only when libpaths are defined.
cc.find_library() also searches in the toolchain directories, and the
static library might be there.
A hard error makes this feature useless in most cases since a static
library usually won't be found for every library, particularly system
libraries like -lm. Instead, warn so the user can provide the static
library if they wish.
This feature will be expanded and made more extensible and more usable
in the future.
