If it isn't, as is the case for MSVS for example, we don't need to set
wxHAVE_CEF_DEBUG anyhow, as it's set automatically if _DEBUG is defined
during the build.

This has the advantage of returning libraries in their load order, which
is more useful than the unspecified order that was used before.
It also means that this function now has a chance of working under other
systems such as FreeBSD, which also provides dl_iterate_phdr().
Disable warnings while compiling the tests to avoid unnecessary noise in
the CMake output/error files (because we don't really care about
warnings in the test code at all) and also, and more importantly, to
ensure that the tests don't fail even when -Werror is specified in the
CMAKE_CXX_FLAGS globally, as it may happen when wxWidgets is used via
add_subdirectory() from a superproject.
See #23665.
This is the standard and there doesn't seem to be any contemporary
systems where this is not the case. The configure check for it was
originally added in 101c20d554 (attempting to fix sa_handler signature
for IRIX, 2000-04-01), but IRIX is not supported/doesn't exist any
longer, so don't waste time on checking for this.
The real motivation for this change is that the test failed in CMake
builds, showing just
-- Performing Test wxTYPE_SA_HANDLER_IS_INT - Failed
in the log and then resulting in -fpermissive warnings when assigning
wxFatalSignalHandler to sa_handler and it's simpler to just remove the
check than to debug it.
See #23664.
Define HAVE_LARGEFILE_SUPPORT and add '_FILE_OFFSET_BITS=64' compile definition.
Make it a PUBLIC definition so it is part of the interface, and defined when importing a target.
Check if fseeko is available, which is used in the large file code.
Also add the compile definition to wxconfig's cppflags, because configure does this too.
Large file support can be disabled with the wxBUILD_LARGEFILE_SUPPORT option, similar to configure's --disable-largefile.
Fixes#22750
Don't use compiler-specific __thread and use the standard keyword
instead.
Keep the existing TLS-related macros for compatibility, but remove our
custom implementation of them, so that they're always trivial now.
Always use std::unordered_{map,set} when we use them at all, don't
bother with checking for their availability and with tr1 or even older
alternatives.
Linux (until recently) defined dlopen() in libdl, but some other
operating systems (such as NetBSD) have it in libc.
Use CMake-provided variable for the name of the library to use for
dlopen() to fix NetBSD build.
See #22644.
Change the minimum version to 3.0. Version 2.8.12 has never worked,
because it does not support the VERSION parameter in project().
Replace GREATER_EQUAL comparisons, these are only supported since 3.7.
Move PCH related code to a separate file, and include it after
options.cmake and init.cmake. Because only then the wxBUILD_PRECOMP
variable is fully initialized.
Closes#22312.
Use version comparison instead of normal comparison for libnotify.
Fix warning if mismatched if statement in FindGNOMEVFS2.
Check for GREATER_EQUAL GTK versions, same as configure does.
Don't check for GTK 1 or define __WXGTK127__. CMake does not support GTK1 and it should not be defined when GTK 2/3/4 is used.
The latter two are always defined in sys/types.h on all Unix systems and
we already define them for MSVC (which doesn't use configure anyhow).
The former type is always defined everywhere.
This type should always be defined in sys/types.h on any non-ancient
Unix system, so don't bother checking for it, which is not only wasteful
but can even be harmful because it can conflict with pid_t definitions
in the other libraries under Windows, where we (wrongly) define it as
int (which is actually a bug in autoconf, which was recently fixed, see
https://savannah.gnu.org/support/index.php?110296) when using CMake.
So just don't define it at all: it should be already defined under Unix
and we don't use it under MSW anyhow.

See #18150.
This check didn't work in configure when using C++17 or later, as
std::bind2nd() is removed in C++17 and so was worse than useless as it
actually prevented --enable-stl from working.
And while it was only done when using C++98 in CMake, it still seems
pretty useless there too as there should be no environments in which
basic stuff like std::vector<> or std::find_if() is not available.
So just remove it entirely.
All still supported versions of MinGW/Cygwin provide w32api.h file, so
there is no need to test for it.
This allows to simplify the code, but also remove the definition of
HAVE_W32API_H from bake- and makefiles and this, in turn, allows to get
rid of extra flags in MinGW format entirely, as we don't support gcc
2.95 for which they were originally needed neither.
Remove separate checks for dlerror() which don't seem to be needed under
any platform any longer.
No real changes, just slim down configure/CMake a tiny bit.
This function is not used any more since e289eb07e1 (Get rid of
non-POSIX code for loading dynlibs on *nix, 2020-05-13), so don't check
for it and don't defined the corresponding HAVE_SHL_LOAD symbol.
Always set a value to ICONV_CONST so it will be defined in setup.h.
Add a check for strtoull to prevent a macro redefined warning.
Link with WebKit framework to fix macOS build with wxUSE_WEBKIT.
The changes in 0a94c1890f where an
incomplete solution.
The apple compiler automatically choses libc++ if the deployment target
is >= 10.9. Lower deployment targets need explicit compiler options
to use libc++.
Don't overwrite options in setup.cmake.
Align text in summary message.
Always set wxUSE_XRC to values of wxUSE_XRC, same as in setup.h.
Disable wxUSE_XRC when expat is disabled.
Commit bc13119494 removed the inclusion of
xlocale.h because it is not (and never was) needed under Linux with
glibc, but it is still needed under macOS, so this (silently) disabled
wxXLocale support under Mac when using configure and broke the build
when using cmake.
Fix both problems by using xlocale.h only if it's available, both in
configure and in cmake.
Add CMake-based build system.
Merge the original branch without any changes except for resolving the
conflict due to moving the contents of .travis.yml to a separate file by
propagating the changes done in this file since then to the new script
and rerunning ./build/update-setup-h and ./build/cmake/update_files.py
to update the file lists changed in the meanwhile.
Closes https://github.com/wxWidgets/wxWidgets/pull/330
Add CMake build system for libraries, tests and samples
update_files.py converts build/files into CMake format.
build/update-setup-h has been modified to update build/cmake/setup.h.in.
