Stephen Kelly e4e5b28c27 cmTarget: Deprecate the LOCATION target property with a policy.
The final location and name of a build-target is not determined
until generate-time. However, reading the LOCATION property from
a target is currently allowed at configure time. Apart from creating
possibly-erroneous results, this has an impact on the implementation
of cmake itself, and prevents some major cleanups from being made.

Disallow reading LOCATION from build-targets with a policy. Port some
existing uses of it in CMake itself to use the TARGET_FILE generator
expression.

Stephen Kelly 66b290e7e2 export(): Process the export() command at generate time.
Make the API for adding targets string based so that it can easily
use cmGeneratorTarget.

Teach the cmIncludeCommand to generate the exported file at
configure-time instead if it is to be include()d.

The RunCMake.ExportWithoutLanguage test now needs a dummy header.h
file as expected error from export() is now reported after the
missing file error.

Stephen Kelly af1f698757 CMP0024: Store the fact of included export in global generator.
Storing it in the makefile means that the policy does not trigger
when include and export are in differing directories.

2013-10-08 09:53:37 -04:00
Daniele E. Domenichelli 73d28d2177 CheckStructHasMember: Add support for C++
Previously if headers required to check if a struct has a member can be
compiled with C++ compiler only, the check would fail because the C
compiler fails.  As a consequence, the result variable would be set to
false, even if the struct has that particular member.

Teach CHECK_STRUCT_HAS_MEMBER to accept a new optional argument LANGUAGE
that allows one to explicitly set the compiler to use.  The new
signature is therefore:

  CHECK_STRUCT_HAS_MEMBER (<struct> <member> <header> <variable>
                           [LANGUAGE <language>])

Brad King 1763c31c3b Set policy CMP0025 to NEW while building CMake itself
CMake is aware of the policy's NEW behavior and the AppleClang compiler
id.  Set the policy to NEW explicitly to avoid the warning and get the
NEW behavior.

Also teach the RunCMake test infrastructure to build tests with
-DCMAKE_POLICY_DEFAULT_CMP0025=NEW to avoid the policy warning
in test output that must match specific regular expressions.

Stephen Kelly 435c912848 export: Add support for INTERFACE_LIBRARY targets 2013-10-07 20:07:27 -04:00
Stephen Kelly 904ff9fe59 export: Add policy CMP0024 to disallow include() of export files
Currently, export() is executed at configure-time.

One problem with this is that certain exported properties like
the link interface may not be complete at the point the export() is
encountered leading to an incorrect or incomplete exported
representation. Additionally, the generated IMPORTED_LOCATION
property may even be incorrect if commands following the export()
have an effect on it.

Another problem is that it requires the C++ implementation of cmake
to be capable of computing the exported information at configure time.
This is a limitation on the cleanup and maintenance of the code. At
some point in the future, this limitation will be dropped and more
implementation will be moved from cmTarget to cmGeneratorTarget.

Stephen Kelly fe732264e9 Add the INTERFACE_LIBRARY target type.
This target type only contains INTERFACE_* properties, so it can be
used as a structural node. The target-specific commands enforce
that they may only be used with the INTERFACE keyword when used
with INTERFACE_LIBRARY targets. The old-style target properties
matching LINK_INTERFACE_LIBRARIES_<CONFIG> are always ignored for
this target type.

The name of the INTERFACE_LIBRARY must match a validity generator
expression. The validity is similar to that of an ALIAS target,
but with the additional restriction that it may not contain
double colons. Double colons will carry the meaning of IMPORTED
or ALIAS targets in CMake 2.8.13.

An ALIAS target may be created for an INTERFACE library.

At this point it can not be exported and does not appear in the
buildsystem and project files are not created for them. That may
be added as a feature in a later commit.

The generators need some changes to handle the INTERFACE_LIBRARY
targets returned by cmComputeLinkInterface::GetItems. The Ninja
generator does not use that API, so it doesn't require changes
related to that.

Brad King 9040ec9117 Do not warn about left paren not separated by a space
Since commit 58e52416 (Warn about arguments not separated by whitespace,
2013-02-16) we warn about arguments not separated by spaces.  Loosen the
warning to not complain about left parens not separated by spaces from
the preceding token.  This is common in code like "if(NOT(X))".

separated by spaces and check that no warning appears.

Stephen Kelly 370bf55415 Add the ALIAS target concept for libraries and executables.
* The ALIAS name must match a validity regex.
* Executables and libraries may be aliased.
* An ALIAS acts immutable. It can not be used as the lhs
  of target_link_libraries or other commands.
* An ALIAS can be used with add_custom_command, add_custom_target,
  and add_test in the same way regular targets can.
* The target of an ALIAS can be retrieved with the ALIASED_TARGET
  target property.
* An ALIAS does not appear in the generated buildsystem. It
  is kept separate from cmMakefile::Targets for that reason.
* A target may have multiple aliases.
* An ALIAS target may not itself have an alias.
* An IMPORTED target may not have an alias.
* An ALIAS may not be exported or imported.

Commit 650e61f8 (Add a convenient way to add the includes install
dir to the INTERFACE., 2013-01-05) introduced an error case for
using the install(TARGETS) command with specified INCLUDES DESTINATION,
but no specified EXPORT set.

It is convenient to use a variable to set the various destinations
for different outputs (as KDE does), and some targets such as
executables are installed but not exported. This was triggering
the error case, but as it is a common case, remove the error.

Brad King 4dc4018553 Teach compiler ABI check to tolerate try_compile COPY_FILE failure
In CMakeDetermineCompilerABI we use try_compile with the COPY_FILE
option to get a copy of the compiled binary used to detect the ABI
information.  We already tolerate the case when compilation fails.
However, when compilation appears to succeed but does not produce the
expected executable the try_compile command immediately reports an error
because the COPY_FILE fails.

Tolerate COPY_FILE failure without stopping the overall configuration
process by using the try_compile COPY_FILE_ERROR option to capture the
error message.  Log the full error to CMakeError.log and simply report
failure to detect the ABI as if compilation had failed.

Teach the RunCMake.Configure test to cover this case and verify that the
messages show up as expected both in stdout and in CMakeError.log.
