Create a <LANG>_COMPILER_LAUNCHER target property (initialized by a
CMAKE_<LANG>_COMPILER_LAUNCHER variable) to specify a compiler launcher
tool. This will supersede the CMAKE_<LANG>_COMPILER_ARG1 approach to
using such tools. The old approach set CMAKE_<LANG>_COMPILER to the
launcher tool while the new approach leaves this variable set to the
actual compiler.
Implement this property for Makefile and Ninja generators. It cannot be
implemented for VS or Xcode generators as the IDE build tools offer no
such hooks.
Enable languages only in the individual test case. Enable the test
everywhere except Visual Studio generators (which do not implement the
properties) and just set fake flags as needed to activate relevant code
paths. Drop unneeded CMAKE_SUPPRESS_REGENERATION which seems to have
been copied from an unrelated test when this test was created.
Create a <LANG>_INCLUDE_WHAT_YOU_USE target property (initialized by a
CMAKE_<LANG>_INCLUDE_WHAT_YOU_USE variable) to specify an IWYU command
line to be run along with the compiler.
Use the KWSys Process "MergeOutput" option to give the child process
the same pipe (or file) for both stdout and stderr. This allows
natural merging of stdout and stderr together instead of merging
on arbitrary buffered read boundaries as before.
This reverts commit 242c3966 (add_custom_command: Diagnose
MAIN_DEPENDENCY limitation, 2015-03-09) and the follow up commit
b372a99a (UseSWIG: Do not use MAIN_DEPENDENCY on custom commands,
2015-03-26).
I misdiagnosed the underlying issue that prompted creation of policy CMP0057.
The actual issue surfaces when a single custom command's MAIN_DEPENDENCY
is listed in more than one target; this issue will have to be addressed
independently.
882f48e5 Link libraries by full path even in implicit directories
318cd370 Help: Add link target for Find Modules section of cmake-developer.7
1535dcd8 Tests: Teach RunCMake to optionally merge command output to stdout
When CMP0003 was first introduced we wanted to link all libraries by
full path. However, some projects had problems on platforms where
find_library would find /usr/lib/libfoo.so when the project really
wanted to link to /usr/lib/<arch>/libfoo.so and had been working by
accident because pre-CMP0003 behavior used -lfoo to link.
We first tried to address that in commit v2.6.0~440 (Teach find_library
to avoid returning library paths in system directories, 2008-01-23) by
returning just "foo" for libraries in implicit link directories. This
caused problems for projects expecting find_library to always return a
full path. We ended up using the solution in commit v2.6.0~366 (...
switch library paths found in implicit link directories to use -l,
2008-01-31). However, the special case for libraries in implicit link
directories has also proven problematic and confusing.
Introduce policy CMP0060 to switch to linking all libraries by full path
even if they are in implicit link directories. Explain in the policy
documentation the factors that led to the original approach and now to
this approach.
Add CROSSCOMPILING_EMULATOR target property for executables. This is used by
subsequent patches to run exectuables created for the target system when
crosscompiling. The property is initialized by the
CMAKE_CROSSCOMPILING_EMULATOR variable when defined.
Add policy CMP0059 to cover this change. The property has been
deprecated since CMake 2.4 anyway.
This will help clean up cmMakefile -- the DefineFlagsOrig member should
not need to exist.

82a37d3c cmGlobalNinjaGenerator: Drop unused member
Add policy CMP0058 to avoid generating 'phony' ninja rules for unknown
custom command dependencies. This requires projects to specify their
custom command byproducts explicitly. With this requirement we no
longer have to assume that unknown custom command dependencies are
generated and can instead simply assume they are source files expected
to exist when the build starts. This is particularly important in
in-source builds. It is also helpful for out-of-source builds to allow
Ninja to diagnose missing files before running custom command rules that
depend on them.
Implement a brand new FindMatlab module:
- Add support for versions and components.
- Find Matlab and its version in a more precise and multiplatform way.
- Add API to create a new mex extension with documentation.
- Add API to add matlab unit tests (with or without the unit test framework).
- Find as much as possible based on a single Matlab_ROOT_DIR cache entry
and allow the user to change it to re-find everything.

Otherwise find_library is unable to lookup the XCTest framework which
is not located in the SDK serach path:
In the 10.10 SDK the SDK frameworks are located here:
$DEVELOPER_DIR/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.10.sdk/System/Library/Frameworks
whereas the Platform SDKs are located here:
$DEVELOPER_DIR/Platforms/MacOSX.platform/Developer/Library/Frameworks

The find_package command already knows how to compute installation
prefixes from PATH. Use the same approach to establish prefixes for
find_library, find_file, and find_path to use to look in directories
like "<prefix>/lib[/<arch>]" and "<prefix>/include" for libraries and
headers. This will reduce the amount of configuration end users need to
do to establish a work environment rooted under a specific prefix.
Several tests use slight variations of the same logic to enable CPack
RPM tests. Consolidate this logic into one check before any tests are
added. Look for 'rpmbuild' only on Linux and only when the test build
tree does not have spaces in the path. In particular, this will make
the result available in time for the RunCMake.CPackRPM test to be
activated even if CMake is configured exactly once.
The moved tests are related to paths in INTERFACE_INCLUDE_DIRECTORIES
in general, and when exporting, and covering cases of the install
location being within the build or source prefix etc. Other build
properties containing paths should have similar tests, so this
allows some parameterization while keeping the preparation of the
various directory structures.
