Stephen Kelly 3917d86b26 Genex: Add a nullary form for CONFIG
This is consistent with other similar expressions such as PLATFORM_ID,
and makes the CONFIGURATION expression obsolete.

Fix an off-by-one error in

Remove the test for 'bad' nullary use of $<CONFIG>.

Add a unit test to verify that $<CONFIG> and $<CONFIGURATION> have
the same value.

Stephen Kelly 84fac67f90 Don't allow include() of export(EXPORT) file at configure time.
As a new feature it does not need to participate in CMP0024.

Store cmExportBuildFileGenerator instances which correspond to the
export(EXPORT) signature in a second map which does not own the
pointers.  This avoids the need to add cmExportBuildFileGenerator
and dependencies to the bootstrap system.

Stephen Kelly c9f9b3cd94 cmTarget: Test impliedByUse number-compatible properties.
Test that it is an error to read a number-compatible property to
determine the link implementation.  An alternative would be to
consider the value to be "0", however, that is too arbitrary
given the use-cases of this feature.  Values from this feature may
be used in setting a define, where "0" may have special or invalid
meaning and should be explicit.

Stephen Kelly 01c545c596 cmTarget: Fix debug report for interface-set compatibility types.
If the dependent target sets the property to boolean false, ensure
that that appears in the debug report.  Previously, the report
output contained whether the property was consistent among dependencies,
displaying 'TRUE', instead of the content of the property, which may
be 'FALSE'.

Return a std::pair from the consistentProperty method.  This makes
it possible to make the return value for string types easier to
reason about.  The return value of consistentProperty was previously
set to an empty static string to emulate a 'true' value for the caller
in commit 816b4a8a (cmTarget: Make consistentProperty
return consistent content., 2013-10-22).  The pair makes the
consistency result properly typed.

Brad King 4ac75fdfe6 Prefer CMAKE_MAKE_PROGRAM over CMAKE_BUILD_TOOL (#14548)
Historically these were both added for the Makefile and Visual Studio
generators, respectively.  Later the VS generators started using the
CMAKE_MAKE_PROGRAM cache entry to find the IDE build tool, and the
CMAKE_BUILD_TOOL was simply set as an alias.

Fix the documentation to explain that CMAKE_MAKE_PROGRAM is the modern
variable and that CMAKE_BUILD_TOOL is the compatibility alias, not the
other way around.  Replace uses of CMAKE_BUILD_TOOL with
CMAKE_MAKE_PROGRAM in CMake-provided modules.  Nothing needs to lookup
CMAKE_BUILD_TOOL in the cache, so simply set it as a normal variable.

Brad King bca67c710f build_command: Return a "cmake --build" command-line
Re-implement the build_command() command to use "cmake --build" instead
of generating a native build tool invocation directly.  This command
will internally invoke the proper native build tool.

This avoids requiring cmGlobalGenerator::GenerateBuildCommand to produce
a string so that it can be later refactored to produce a vector with no
quoting or escaping.  It will also allow us to later teach CMake to
delay the decision about which build tool to invoke until after the
project build system is generated to disk.  For example, on Visual
Studio 10 and above the preferred command-line tool is MSBuild, but we
need to fall back to devenv if the .sln has Intel Fortran .vfproj files.

Brad King 0a561a0347 CMP0022: Warn about a given target at most once
Since cmTarget::ComputeLinkInterface is called separately for each
"head" target that links a target, the warning we produce when
CMP0022 is not set could be repeated.  Add explicit logic to allow
the warning to appear at most once.  Multiple copies of the warning
for the same target are almost always identical and therefore
redundant.  In the rare case that two copies of the warning are
different, the second can appear in a future run after the first
is fixed.

Brad King 23d21b78e1 Do not export INTERFACE_LINK_LIBRARIES from non-linkable targets
When cmExportFileGenerator::SetImportLinkInterface exports the old
LINK_INTERFACE_LIBRARIES property values it skips doing so for
non-linkable targets because target->GetLinkInterface returns NULL for
such targets.

Since cmExportFileGenerator::PopulateInterfaceLinkLibrariesProperty
looks at the INTERFACE_LINK_LIBRARIES property directly instead of using
the computed link interface, teach it to skip exporting the property if
target->IsLinkable returns false.

Extend the RunCMake.CMP0022 test with a case covering this.  Simply
export an executable target that links to a library that is not
exported.

Brad King ef10b87cc1 CMP0022: Plain target_link_libraries must populate link interface
The CMP0022 NEW behavior is that the INTERFACE_LINK_LIBRARIES property
exactly defines the link interface.  The plain target_link_libraries
signature says linking is transitive by default, so it should populate
the property.

Teach the target_link_libraries plain signature to populate the
INTERFACE_LINK_LIBRARIES regardless of the CMP0022 setting.  Refactor
the cmTarget::ComputeLinkInterface checks that warn when the policy is
not set to compare the new property to either the explicitly set old
link interface properties or the link implementation fallback for all
linkable target types, not just static libraries.

This fixes a regression in 2.8.12.0 that caused target_link_libraries to
not implement transitive linking in the plain signature once the policy
CMP0022 is set to NEW.

All generators now support detection of the full path to the compiler, so

other logic to assume the full path to the compiler tool is available.

The Makefile generators already rejected CMAKE_<LANG>_COMPILER values
that did not name an existing compiler.  Extend this error message to
all generators, make it occur as early as possible, and improve the
message with advice about how to set the compiler.  If the full path to
the compiler is not known, finish enabling languages with a fatal error
so configuration does not continue.

For now, allow the RC language compiler to not be a full path.  Later we
will need to detect the full path to "rc" under the VS IDE.

Add a RunCMake.CompilerNotFound test to cover failure cases.

Brad King efcf318f8d Add \-continuation to CMake language quoted arguments
Teach the CMake language lexer to treat the \-LF pair terminating a
line ending in an odd number of backslashes inside a quoted argument
as a continuation.  Drop the pair from the returned quoted argument
token text.  This will allow long lines inside quoted argument
strings to be divided across multiple lines in the source file.
It will also allow quoted argument text to start on the line after
the opening quote.  For example, the code:

 set(x "\
 ...")

sets variable "x" to the value "..." with no opening newline.

Previously an odd number of backslashes at the end of a line inside
a quoted argument would put a \-LF pair (or a \-CR pair) literally
in the argument.  Then the command-argument evaluator would complain
that the \-escape sequence is invalid.  Therefore this syntax is
available to use without changing behavior of valid existing code.

Teach the RunCMake.Syntax test to cover cases of quoted arguments
with lines ending in \, \\, and \\\.  Odd counts are continuations.

Brad King daa0f6f98d Add Lua-style long brackets and long comments to CMake language
Teach the CMake language parser to recognize Lua-style "long bracket"
arguments.  These start with two '[' separated by zero or more '='
characters e.g. "[[" or "[=[" or "[==[".  They end with two ']'
separated by the same number of '=' as the opening bracket.  There is no
nesting of brackets of the same level (number of '=').  No escapes,
variable expansion, or other processing is performed on the content
between such brackets so they always represent exactly one argument.

Also teach CMake to parse and ignore "long comment" syntax.  A long
comment starts with "#" immediately followed by an opening long bracket.
It ends at the matching close long bracket.

Teach the RunCMake.Syntax test to cover long bracket and long comment
cases.

Inside of a command invocation, the parser treats an identifier as an
unquoted argument.  Therefore this change to the lexer will make what

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.

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>

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.
2013-10-07 19:57:06 -04:00
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.

Stephen Kelly 650e61f833 Add a convenient way to add the includes install dir to the INTERFACE.
Export the INCLUDES DESTINATION without appending to the
INTERFACE_INCLUDE_DIRECTORIES of the target itself. That way, a target
can be exported multiple times with different INCLUDES DESTINATION
without unintended cross-pollution of export sets.

Stephen Kelly 4f6bd7022b Remove the LINK_LANGUAGE generator expression.
It accepted an optional argument to test for equality, but no way
to get the linker language of a particular target.

TARGET_PROPERTY provides this flexibility and STREQUAL provides
the necessary API for equality test.

Extend the CompileDefinitions test to cover accessing the
property of another target.

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.
