The fix from commit eafe740ead (FindXCTest: Fix output directory for
test bundle with new build system, 2021-02-09, v3.19.5~5^2) is not
necessary with Xcode 12.5, which seems to have changed/fixed the
behaviour again.
Fixes: #22462
These have been added to:
GCC_PREPROCESSOR_DEFINITIONS
OTHER_CFLAGS
OTHER_LDFLAGS
This is to allow Cocoapods to work correctly as it uses xcconfig files to alter build settings in Xcode, and requires these build settings to inherit from their parent, not overwrite.
Xcode 12 doesn't allow nested builds within the same build directory.
That means we can no longer do an install by building the install target
when IOS_INSTALL_COMBINED is true. We can, however, still do an install
by running the cmake_install.cmake script or executing cmake --install,
since there is no outer build and therefore the associated SDK can be
built as a sub-build.
The non-build methods previously didn't work when
IOS_INSTALL_COMBINED was true because the generated install script
and the CMakeIOSInstallCombined script both made certain assumptions
that relied on being part of a build. Those assumptions are now
removed. A side-effect of this work is that cpack now also works from the
command line when IOS_INSTALL_COMBINED is true.

Generalize the change from commit bffb17be3d (Xcode: Inherit target
library and framework search paths from project, 2020-11-04,
v3.19.0-rc3~4^2) to apply to framework and other kinds of search paths
added either for include directories or for linking.

Support of 'new build system' in Xcode fixes indirectly few issues
which were caused by workaround with `XCODE_DEPEND_HELPER.cmake`
autogenerated script.
This patch adds test which is originated from issue #20260 and
reproduces this issue when 'new build system' is disabled.
Fixes: #20260
The new Xcode 12 build system does not support recursive
invocation. Therefore lazily triggered builds for the
corresponding platform which run during the `install` target
fail with:
```
error: unable to attach DB: error: accessing build database
```
While looking for a work-around we conditionally disable those
tests.
Issue: #21206
The Xcode "new build system" selects different architectures for device
builds than the old build system does. Skip those tests on Xcode 12+
pending further investigation.
Issue: #21206
OBJECT and STATIC libraries (framework or non-framework) do not use
this build phase. Not all items to be linked use this build phase either.

The XcodeRemoveExcessiveISystem test runs
`find_package(ZLIB)` which returns an SDK-relative
path to `zlib.tlb`. When the test switches the SDK
for building to something different than the SDK used
for configuration the linker rightfully complains about
the mismatch.
The fix is to configure and build with the same SDK.
INTERFACE libraries were created with the intention of collecting usage
requirements for use by other targets via `target_link_libraries`.
Therefore they were not allowed to have SOURCES and were not included in
the generated buildsystem. In practice, this has become limiting:
* Header-only libraries do have sources, they just do not compile.
Developers should be able to edit those sources (the header files)
in their IDE.
* Header-only libraries may need to generate some of their header
files via custom commands.
Some projects work around these limitations by pairing each interface
library with an `add_custom_target` that makes the header files and
custom commands appear in the generated buildsystem and in IDEs.
Lift such limitations by allowing INTERFACE libraries to have SOURCES.
For those with sources, add a corresponding build target to the
generated buildsystem.

Populate `CMAKE_Swift_IMPLICIT_INCLUDE_DIRECTORIES` with the macOS SDK's
include directory so that we filter such implicit directories out of
Swift targets.
Fixes: #19845
When CMAKE_XCODE_GENERATE_TOP_LEVEL_PROJECT_ONLY is set on
Xcode generator created post build scripts which tried to call
XCODE_DEPEND_HELPER.make script in subproject.
But XCODE_DEPEND_HELPER.make don't exist in
subprojects when mentioned option is set on.

Add `XCODE_SCHEME_*` target properties and associated variables
`CMAKE_XCODE_SCHEME_*` to initialize them on target creation.
Map each target property value to an associated Xcode scheme entry.

Since commit v3.11.0-rc1~467^2 (VS,Xcode: Add CMakeLists.txt sources
without mutating targets, 2017-10-18) we do not add `CMakeLists.txt` to
target sources but instead generate references to them directly. This
broke projects that explicitly specify their `CMakeLists.txt` file as a
source file because the explicit entry is no longer consolidated with
the generated one.
Teach the relevant generators to avoid duplicating `CMakeLists.txt`
source references and add test cases.
Fixes: #17828
In case CMAKE_XCODE_GENERATE_TOP_LEVEL_PROJECT_ONLY has been enabled
generate only the root-level ZERO_CHECK target so targets in
subdirectories pick up the root generator target of ZERO_CHECK.
For the case that CMAKE_XCODE_GENERATE_TOP_LEVEL_PROJECT_ONLY is not
enabled more investigation and a proper and final fix is still needed.
Issue: 14297
When building with multiple SDKs within one project Xcode requires
the usage of ${EFFECTIVE_PLATFORM_NAME} to put temporary and build
outout into separate directories. For example an iOS device and
simulator build use two different SDKs (iphoneos and iphonesimulator).
In the past cmake tries to detect embedded toolchains that could
possibly use simulators and emitted EFFECTIVE_PLATFORM_NAME (EPN)
at the proper locations. In #16253 Mark noticed that if he
uses macosx and iphoneos in combination the necessary EPN is not
emitted. This is because CMake by default assumes macosx SDK which
does not trigger EPN emission.
The fist naive approach - enabling EPN unconditionally revealed that
then the EPN leaks into generator expressions like $<TARGET_FILE:xxx>
which might be a regression and thus is unacceptable.
The next approach was to add an CMake property to enable EPN emission
unconditionally. This solved the reported problem.
But the EPN leakage also happened for the embedded toolchains already
without anyone noticing. So the control property was turned into a
tri-state one:
* No definition: EPN is activated for embedded toolchains like before
* ON: EPN is always emitted
* OFF: EPN is never emitted
That approach gives the user the chance to disable EPN for embedded
toolchains and restores generator expression functionality for those.
Closes: #16253
Refactoring in commit v3.5.0-rc1~272^2~16 (cmGeneratorTarget: Add API for
property keys, 2015-10-25) changed the Xcode generator implementation of
`XCODE_ATTRIBUTE_...` properties to use the target `GetProperty` method on each
`XCODE_ATTRIBUTE_...` property listed by `GetPropertyKeys` instead of looping
over the property entries directly. This made the lookup of property names of
the form `XCODE_ATTRIBUTE_..._LOCATION` accidentally trigger the computed
property logic for the undocumented/legacy `<CONFIG>_LOCATION` property. Of
course the computed property value is not the same as the value stored in the
`XCODE_ATTRIBUTE_..._LOCATION` property. Fix the computed property logic to
avoid triggering on `XCODE_ATTRIBUTE_...` attributes.
Closes: #16319
If list of valid target architectures is empty for given SDK then there will
be no VALID_ARCHS build setting returned by Xcode. Return "" (empty string)
explicitly in this case. This may happens if CMAKE_IOS_INSTALL_COMBINED is ON
but only one architecture used in target.
Before this change backslashes in strings were escaped during compile
flags adds via AppendFlag(). But global flags like OTHER_CPLUSPLUSFLAGS
are not added as flags but as plain strings so they were not escaped
properly.
Now the escaping is performed within cmXCodeObject::PrintString() which
ensures that strings are always encoded.
This patch solves the problem of installing both: Device and Simulator
libraries on iOS. Before only one of them was installed.
If the IOS_INSTALL_COMBINED property is set on a target, a
special install hook will be activated which builds the corresponding
target and combines both at the install location.
The original patch was contributed by Ruslan Baratov, and polished by
Gregor Jasny.

Starting with Xcode 7 the OSX and iOS SDKs contain only stub
files for dynamic system libraries. These stub files contain
some meta data and a list of exported sysbols in plain text.
They are handled by the toolchain like regular dylibs.
