CMake support for c++23 was added in 3.20.
Remove statements explicitly setting the following policies to NEW.
These policies were introduced in or before 3.20, and now that 3.20 is
the minimum version they will automatically have the NEW behavior.
Policy: Introduced in
CMP0079: 3.13
CMP0084: 3.14
CMP0091: 3.15
CMP0092: 3.15
CMP0099: 3.17
CMP0117: 3.20
Disable scanning c++ source files for module imports (introduced as
CMP0155 in 3.28) since we don't use modules and that policy triggers
build errors with Clang if the clang-scan-deps tool isn't installed.
cpp-ipc is explicitely only available on Windows, Linux, QNX, and FreeBSD. Trying to build dolphin on any another BSD such as OpenBSD or Haiku currently leads to failure because of this.
OProfile is not used at all these days, most major distributions do not ship it anymore (Debian, Fedora, and Alpine to name the few I've checked) and following a discussion on Discord, nobody is apparently using it, most devs not even being aware of it. This removes an optional dependency from Dolphin.
Some generators (like Unix Makefiles and Xcode) copy an app's Info.plist at configure time.
This causes a problem when we need to generate the Info.plist at build time, like how we
currently do it with ScmRevGen. Instead of generating the Info.plist directly in ScmRevGen,
provide an Info.plist without any version information to CMake at configure time, have
ScmRevGen generate a separate plist file with the version information at build time, and
then merge the two together to create the final Info.plist.
This reverts commit 6dad8f8372.
Our bundled zlib-ng uses zlib compat mode, making it override system zlib.
System zlib-ng will not, and all its functions will be prefixed with zng_.
Therefore the two aren't actually compatible.
Dolphin currently fails to build when the Linux system building it includes headers/pkgconfigs for minizip-ng built in both minizip-ng mode and legacy compat mode (the minizip API).
This is because minizip-ng is checked for in cmake however the code is not actually compatible against minizip-ng built in non-legacy mode. Until that is rectified Dolphin should just check for a pkgconfig for minizip. If the system has a pkgconfig for minizip with a version >= 4 then the system package is minizip-ng built in compat mode which is exactly what we want.
