Brad King a6d3ffcb1f Fix Module.ExternalData test on VS 6
Run the test with the ctest --build-noclean option.  The test
CMakeLists.txt file already uses file(REMOVE_RECURSE) to clean out
downloaded data anyway.  Some file removed by "msdev ... /clean" causes
CMake to re-run in the middle of the build step and file(REMOVE_RECURSE)
wipes out already-generated files.

Stephen Kelly 77cecb778f Add includes and compile definitions with target_link_libraries.
This establishes that linking is used to propagate usage-requirements
between targets in CMake code. The use of the target_link_libraries
command as the API for this is chosen because introducing a new command
would introduce confusion due to multiple commands which differ only in
a subtle way.

Brad King 19f3208a06 Tests: Avoid CTestLimitDashJ crash on Borland 5.8 builds
The test added by commit e378ba5f (Add CTestLimitDashJ test, 2012-12-26)
crashes with CTest compiled by Borland 5.8.  There seems to be interaction
among the large number of internal ctest runs.  It is probably related to
the undiscovered underlying issue mentioned in commit 32478069 (CTest:
Prevent creation of unbounded number of tests in ctest, 2012-12-18) when
fixing the symptom covered by the CTestLimitDashJ test.

Add --force-new-ctest-process to avoid the crash.  Further investigation
will still be needed to identify the true problem.

Stephen Kelly b98d14d400 Disallow porcelain to populate includes and defines of IMPORTED targets.
With similar reasoning to the parent commit, as downstreams, we can't
determine what $<CONFIG> generator expressions would be appropriate.

Upstream would have populated the INTERFACE_INCLUDE_DIRECTORIES with
config-specific generator expressions, possibly appropriate for
their DEBUG_CONFIGURATIONS. In theory, if we would add include
directories for a DEBUG intent, we would have to match the upstream
configurations for that.

Rather than attempting to discover the appropriate configurations
at this time, simplify the feature instead. The use of IMPORTED targets
with these commands could still be added in the future if targets
would export their DEBUG_CONFIGURATIONS somehow.
2013-01-21 12:32:46 +01:00
Stephen Kelly 48a4cf2182 Revert "Allow target_link_libraries with IMPORTED targets."
This reverts commit 9cfe4f1b76.

It turns out that correctly adding the content to
the IMPORTED_LINK_INTERFACE_LIBARIES_<CONFIG> of an upstream target
from the buildsystem of a downstream project is not simple.

If upstream had added the INTERFACE content, the config-specific
properties would  be determined by the DEBUG_CONFIGURATIONS of
upstream.

As downstream, we don't have any information about what
the DEBUG_CONFIGURATIONS of upstream were, so we can't determine
which configuration-specific properties to populate. The best we can do
is add it to all of them or add it to the ones downstream considers to
be DEBUG_CONFIGURATIONS, neither of which is a good solution.

So, removing the porcelain API for that is the best approach. A human
can still determine which properties to populate and use
the set_property API to populate the desired properies.

Another solution to this would be for upstream targets to publish
what they consider DEBUG_CONFIGURATIONS, but that can be added in
a future release.

Stephen Kelly 0d46e9a029 Store includes from the same include_directories call together.
Otherwise, we get a separate IncludeDirectoriesEntry for each include,
and that causes unnecessary and confusing splitting in the output when

Brad King bc65b74fa6 VS11: Fix VSExternalInclude test
Set CMAKE_SUPPRESS_REGENERATION in the Lib1 and Lib2 projects so that
their .vcxproj files do not contain references to ZERO_CHECK.  Such
references do not make sense when using the files in another .sln file.
This does not reduce the effectiveness of the test because real projects
that use include_external_msproject will have their own .vcxproj files not
generated by CMake anyway.

Brad King c0f1af926f ExternalProject: Allow DEPENDS on normal targets (#13849)
The ExternalProject_Add DEPENDS option adds two types of dependencies.
It adds a target-level build order dependency between the external
project target and the named targets.  It also adds a file-level
dependency on the "done" stamp file of the named external project
targets.  Targets not created by ExternalProject_Add have no such stamp
file and no _EP_STAMP_DIR property.  Prior to commit d14c0243 (Refactor
repeated code into function, 2012-04-26) we unconditionally accepted an
empty stamp dir and generated a dependency on a non-existent file.
After that commit we generate an error that no stamp dir is set.

Skip the file-level dependency when the named dependency is not an
external project target in order to allow this use case.  Teach the
ExternalProject test to cover the case.

Stephen Kelly 77d2646784 Allow generator expressions in LINK_INTERFACE_LIBRARIES.
The Config and IMPORTED_ variants may also contain generator
expressions.

If 'the implementation is the interface', then the result of
evaluating the expressions at generate time is used to populate
the IMPORTED_LINK_INTERFACE_LIBRARIES property.

1) In the case of non-static libraries, this is fine because the
  user still has the option to populate the LINK_INTERFACE_LIBRARIES
  with generator expressions if that is what is wanted.

2) In the case of static libraries, this prevents a footgun,
  enforcing that the interface and the implementation are really
  the same.

  Otherwise, the LINK_LIBRARIES could contain a generator
  expression which is evaluated with a different context at build
  time, and when used as an imported target. That would mean that the
  result of evaluating the INTERFACE_LINK_LIBRARIES property for
  a static library would not necessarily be the 'link implementation'.

  For example:

    add_library(libone STATIC libone.cpp)
    add_library(libtwo STATIC libtwo.cpp)
    add_library(libthree STATIC libthree.cpp)

    target_link_libraries(libtwo
      $<$<STREQUAL:$<TARGET_PROPERTY:TYPE>,STATIC_LIBRARY>:libone>)
    target_link_libraries(libthree libtwo)

  If the LINK_LIBRARIES content was simply copied to the
  IMPORTED_LINK_INTERFACE_LIBRARIES, then libthree links to libone, but
  executables linking to libthree will not link to libone.

3) As the 'implementation is the interface' concept is to be
  deprecated in the future anyway, this should be fine.

If the headers are in CMAKE_CURRENT_SOURCE_DIR, and the generated headers
are in CMAKE_CURRENT_BINARY_DIR, this is a convenient way to build a target
bar, which depends on foo, just by using target_link_libraries() and adding
the INTERFACE_INCLUDE_DIRECTORIES to the INCLUDE_DIRECTORIES of the target
being linked. There will be more-convenient porcelain API to consume the
property in the future.

Stephen Kelly 7653862798 Add LINK_LIBRARIES property for direct target link dependencies
Previously we kept direct link dependencies in OriginalLinkLibraries.
The property exposes the information in the CMake language through the
get/set_property commands.  We preserve the OriginalLinkLibraries value
internally to support old APIs like that for CMP0003's OLD behavior, but
the property is now authoritative.  This follows up from commit d5cf644a
(Split link information processing into two steps, 2012-11-01).

This will be used later to populate the link interface properties when
exporting targets, and will later allow use of generator expressions
when linking to libraries with target_link_libraries.

Also make targets depend on the (config-specific) union of dependencies.
CMake now allows linking to dependencies or not depending on the config.
However, generated build systems are not all capable of processing
config-specific dependencies, so the targets depend on the union of
dependencies for all configs.

Stephen Kelly 57a67bf27e Qt4: Add module dependencies to the IMPORTED targets
This means for example, that consumers can use:

 target_link_libraries(foo ${QT_QTGUI_LIBRARIES})

instead of also needing to specify all 'public' dependencies:

 target_link_libraries(foo ${QT_QTGUI_LIBRARIES} ${QT_QTCORE_LIBRARIES} )

when using the IMPORTED targets.  Also populate the
IMPORTED_LINK_DEPENDENT_LIBRARIES property so CMake can help the linker
find shared library dependencies.

Stephen Kelly b2f1700bc7 GenEx: Add expressions to specify build- or install-only values
This is for specifying INCLUDE_DIRECTORIES relevant to the build-location
or the install location for example:

 set_property(TARGET foo PROPERTY
   INTERFACE_INCLUDE_DIRECTORIES
   "$<BUILD_INTERFACE:${CMAKE_CURRENT_BINARY_DIR};${CMAKE_CURRENT_SOURCE_DIR}>"
   "$<INSTALL_INTERFACE:${CMAKE_INSTALL_PREFIX}/include>"
 )

A 'bar' target can then use:

 set_property(TARGET bar PROPERTY
   INCLUDE_DIRECTORIES
   "$<TARGET_PROPERTY:foo,INTERFACE_INCLUDE_DIRECTORIES>"
 )

and it will work whether foo is in the same project, or an imported target
from an installation location, or an imported target from a build location
generated by the export() command.

Because the generator expressions are only evaluated at build-time, these
new expressions are equivalent to the ZeroNode and OneNode.

The GeneratorExpression test is split into parts. Some shells can't run
the custom command as it is getting too long.

David Cole e378ba5f39 Add CTestLimitDashJ test (#12904)
Add a test that verifies that when ctest -j 4 is called, at most, 4 tests
are executed at any one time.

The test works by running the same script as each of 100 tests. And then setting
up test properties for DEPENDS, RUN_SERIAL, PROCESSORS and COST in order to get
the tests to run in a semi-deterministic ordering, even in parallel. The script
writes a file, sleeps for a bit, and then deletes the file. In the meantime, it
counts files that currently exist, and emits output that triggers a test failure
if the count of files is ever greater than 4.

Prior to the commit that fixed bug #12904, this would result in a failed test
because the output of some of the tests would indicate that more than 4 tests
were running simultaneously.

Now that this issue is resolved, this test will help guarantee that it stays
resolved moving forward.

Brad King cc676c3a08 OS X: Detect implicit linker framework search paths
Previously we hard-coded a list of implicit framework directories but
did not account for CMAKE_OSX_SYSROOT or for changes to the list across
OS X versions.  Instead we should automatically detect the framework
directories for the active toolchain.

The parent commit added the "-Wl,-v" option to ask "ld" to print its
implicit directories.  It displays a block such as:

 Framework search paths:
	/...

Parse this block to extract the list of framework directories.

Detection may fail on toolchains that do not list their framework
directories, such as older OS X linkers.  Always treat the paths

 <sdk>/Library/Frameworks
 <sdk>/System/Library/Frameworks
 <sdk>/Network/Library/Frameworks # Older OS X only
 /System/Library/Frameworks

as implicit.  Note that /System/Library/Frameworks should always be
considered implicit so that frameworks CMake finds there will not
override the SDK copies.

Brad King 2dd67c7ea0 OS X: Detect implicit link directories on modern toolchains
We detect the implicit link directories for the toolchain by adding a
flag to get verbose output from the compiler front-end while linking the
ABI detection binary.  Newer OS X toolchains based on Clang do not add
the implicit link directories with -L options to their internal
invocation of "ld".  Instead they use a linker that comes with the
toolchain and is already configured with the proper directories.

Add the "-Wl,-v" option to ask "ld" to print its implicit directories.
It displays them in a block such as:

 Library search paths:
	/...

Parse this block to extract the implicit link directories.

While at it, remove the checks introduced by commit efaf335b (Skip
implicit link information on Xcode, 2009-07-23) and commit 5195a664
(Skip implicit link info for multiple OS X archs, 2009-09-22).  Discard
the non-system link directories added by Xcode.  Discard all detected
implicit libraries in the multi-architecture case but keep the
directories.  The directories are still useful without the libraries
just to suppress addition of explicit -L options for them.

711b63f Add policy CMP0019 to skip include/link variable re-expansion
2012-12-11 13:44:08 -05:00
Brad King 711b63f7e0 Add policy CMP0019 to skip include/link variable re-expansion
Historically CMake has always expanded ${} variable references in the
values given to include_directories(), link_directories(), and
link_libraries().  This has been unnecessary since general ${}
evaluation syntax was added to the language a LONG time ago, but has
remained for compatibility with VERY early CMake versions.

For a long time the re-expansion was a lightweight operation because it
was only processed once at the directory level and the fast-path of
cmMakefile::ExpandVariablesInString was usually taken because values did
not have any '$' in them.  Then commit d899eb71 (Call
ExpandVariablesInString for each target's INCLUDE_DIRECTORIES,
2012-02-22) made the operation a bit heavier because the expansion is
now needed on a per-target basis.  In the future we will support
generator expressions in INCLUDE_DIRECTORIES with $<> syntax, so the
fast-path in cmMakefile::ExpandVariablesInString will no longer be taken
and re-expansion will be very expensive.

Add policy CMP0019 to skip the re-expansion altogether in NEW behavior.
In OLD behavior perform the expansion but improve the fast-path
heuristic to match ${} but not $<>.  If the policy is not set then warn
if expansion actually does anything.  We expect this to be encountered
very rarely in practice.
