Brad King 82d4317503 Allow projects to specify extra inputs to CMake
Define a new 'CMAKE_CONFIGURE_DEPENDS' directory property that projects
can use to specify input files to the CMake configuration process.
Extend the RunCMake.Configure test to verify that the build system
re-runs CMake when this input changes.

Rolf Eike Beer c768e398f9 cmMakefile: make some methods take const std::string& instead of const char*
Most callers already have a std::string, on which they called c_str() to pass it
into these methods, which internally converted it back to std::string. Pass a
std::string directly to these methods now, avoiding all these conversions.
Those methods that only pass in a const char* will get the conversion to
std::string now only once.

Stephen Kelly 84218e1870 Add automatic uic invocation for Qt.
The source files are already processed by cmQtAutomoc to look for
moc includes, so extend that to also look for ui_ includes and
find corresponding .ui files to process.

This replaces the need to invoke qt4_wrap_ui().

As the ui files are not likely to be part of the SOURCES of the
target, store the options associated with them separately in the
cmMakefile for querying during the autogen run.

Brad King 7d47c69365 Drop compatibility with CMake < 2.4
Drop all behavior activated by setting CMAKE_BACKWARDS_COMPATIBILITY to
a value lower than 2.4, and generate an error when projects or the user
attempt to do so.  In the error suggest using a CMake 2.8.x release.

Teach cmake_minimum_required to warn about projects that do not require
at least CMake 2.4.  They are not supported by CMake >= 3.0.

Replace the documentation of CMAKE_BACKWARDS_COMPATIBILITY with a
reference to policy CMP0001.

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.
2013-10-10 12:01:39 +02:00
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.

Nicolas Despres 2268c41a05 Optimize custom command full-path dependency lookup
In the common case of custom command dependencies specified via full

search.  In the non-full-path case fall back to the existing linear
suffix search.

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.

Stephen Kelly d7dd01083a Add target property debugging for COMPILE_DEFINITIONS
Use constructs similar to those for COMPILE_OPTIONS. This is a little
different because there is a command to remove_definitions(), so

Robert Maynard 6dbd4a5f17 cmMakefile: Refactor AddCMakeDependFile and AddCMakeOutputFile.
AddCMakeDependFile and AddCMakeOutputFile both store as std::string

2013-06-24 10:43:20 -04:00
Stephen Kelly a984f3257e Introduce add_compile_options command.
This command is similar to add_definitions, in that it affects
the compile options of all targets which follow it. The implementation
is similar to the implementation of the include_directories command,
in that it is based on populating a COMPILE_OPTIONS directory property
and using that to initialize the same property on targets.

Unlike the include_directories command however, the add_compile_options
command does not affect previously defined targets. That is, in
the following code, foo will not be compiled with -Wall, but bar
will be:

 add_library(foo ...)
 add_compile_options(-Wall)
 add_library(bar ...)

Stephen Kelly 1714c27a74 Process generator expressions for 'system' include directories.
Since commit 08cb4fa4 (Process generator expressions in the
INCLUDE_DIRECTORIES property., 2012-09-18), it is possible to use
generator expressions with the include_directories command.

As that command can also have a SYSTEM argument, ensure that the
result of using that argument with generator expressions gives a
sane result.

Stephen Kelly d70204a86a Only output includes once after the start of 'generate-time' when debugging.
During configure-time, GetIncludeDirectories may be called too, for example
if using the export() command. As the content can be different, it should
be output each time then.

Stephen Kelly 0d46e9a029 Store includes from the same include_directories call together.
Otherwise, we get a separate IncludeDirectoriesEntry for each include,

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.

2012-05-01 14:09:59 -04:00
Modestas Vainius e1409ac59b Support building shared libraries or modules without soname (#13155)
Add a boolean target property NO_SONAME which may be used to disable
soname for the specified shared library or module even if the platform
supports it.  This property should be useful for private shared
libraries or various plugins which live in private directories and have
not been designed to be found or loaded globally.

Replace references to <CMAKE_SHARED_LIBRARY_SONAME_${LANG}_FLAG> and
hard-coded -install_name flags with a conditional <SONAME_FLAG> which is
expanded to the value of the CMAKE_SHARED_LIBRARY_SONAME_${LANG}_FLAG
definition as long as soname supports is enabled for the target in
question.  Keep expanding CMAKE_SHARED_LIBRARY_SONAME_${LANG}_FLAG in
rules in case third party projects still use it.  Such projects would
not yet use NO_SONAME so the adjacent <TARGET_SONAME> will always be
expanded.  Make <TARGET_INSTALLNAME_DIR> NO_SONAME aware as well.  Since
-install_name is soname on OS X, this should not be a problem if this
variable is expanded only if soname is enabled.

The Ninja generator performs rule variable substitution only once
globally per rule to put its own placeholders.  Final substitution is
performed by ninja at build time.  Therefore we cannot conditionally
replace the soname placeholders on a per-target basis.  Rather than
omitting $SONAME from rules.ninja, simply do not write its contents for
targets which have NO_SONAME.  Since 3 variables are affected by
NO_SONAME ($SONAME, $SONAME_FLAG, $INSTALLNAME_DIR), set them only if
soname is enabled.

Teach cmMakefile::AddCustomCommandToOutput to return the cmSourceFile

instead of separately adding a .rule extension and searching for the
source.  Mark CMake-generated .rule files explicitly with a property

Brad King ca39c5cdd1 Optionally allow IMPORTED targets to be globally visible
Consider the case motivating commit e01cce28 (Allow add_dependencies()
on imported targets, 2010-11-19).  An imported target references a file
generated at build time by a custom target on which it depends.  Had the
file been built directly using add_library or add_executable its target
name would have been visible globally.  Therefore the imported target
representing the file should be globally visible also.

Teach the IMPORTED signature of add_(executable|library) to accept a new
"GLOBAL" option to make the imported target visible globally.

Brad King 9a77f65da7 Remove CMake Policy CMP0015 until it is revised
We revert commit "Create CMake Policy CMP0015 to fix set(CACHE)" because

  option(BUILD_SHARED_LIBS "..." ON)
  add_library(mylib ...)
  set(BUILD_SHARED_LIBS OFF) # we want only mylib to be shared
  add_subdirectory(ThirdParty)

  # ThirdParty/CMakeLists.txt
  option(BUILD_SHARED_LIBS "..." ON)
  # uh, oh, with NEW behavior this dir uses shared libs!!!

We'll re-introduce the policy later with a different change in behavior
to resolve the motivating case, which was more subtle but less common.

The try_compile command builds the cmTryCompileExec executable using the

Brad King fd10589995 ENH: Improve dynamic variable scope implementation
Previously each new variable scope (subdirectory or function call) in
the CMake language created a complete copy of the key->value definition
map.  This avoids the copy using transitive lookups up the scope stack.
Results of queries answered by parents are stored locally to maintain
locality of reference.

The class cmDefinitions replaces cmMakefile::DefinitionsMap, and is
aware of its enclosing scope.  Each scope stores only the definitions
set (or unset!) inside it relative to the enclosing scope.

Brad King c790b1fabb ENH: Create CMP0013 to disallow duplicate dirs
In CMake 2.6.3 and below we silently accepted duplicate build

considured purely a bug that confused beginners but would not be used in
a real project.  In CMake 2.6.4 we explicitly made it an error.

However, some real projects took advantage of this as a "feature" and
got lucky that the subtle build errors it can cause did not occur.
Therefore we need a policy to deal with the case more gracefully.

next entry too.  This also gives the internal interface to create a weak
entry the option to provide an initial PolicyMap for it.

Brad King dfc181a1dc ENH: Create policy scope barriers
This creates a barrier mechanism to prevent user code from using
cmake_policy(POP) to pop a scope it didn't push with cmake_policy(PUSH).
2009-01-22 10:57:16 -05:00
Brad King ac14b5d2eb ENH: Make policy push/pop methods private
This makes cmMakefile::PushPolicy and cmMakefile::PopPolicy private so
that any outside place that uses them needs to use the PolicyPushPop
helper in an automatic variable.  We grant an exception to
cmCMakePolicyCommand so it can implement cmake_policy(PUSH) and
cmake_policy(POP).
2009-01-22 10:57:09 -05:00
Brad King a01eb6b27b ENH: Create automatic policy push/pop helper
This creates cmMakefile::PolicyPushPop to push and pop policy scope
automatically.  It also enforces balanced push/pop pairs inside the
scope it handles.

Brad King 8997f4760a ENH: Refactor policy stack representation
This defines PolicyMap as a public member of cmPolicies.  Its previous
role as a policy stack entry is now called PolicyStackEntry and
represented as a class to which more information can be added later.

Brad King 1dcc5b4558 ENH: Better handling of mismatched blocks
If a logical block terminates with mismatching arguments we previously
failed to remove the function blocker but replayed the commands anyway,
which led to cases in which we failed to report the mismatch (return
shortly after the ending command).  The recent refactoring of function
blocker deletion changed this behavior to produce an error on the ending
line by not blocking the command.  Furthermore, the function blocker
would stay in place and complain at the end of every equal-level block
of the same type.

This teaches CMake to treat the begin/end commands (if/endif, etc.) as
correct and just warns when the arguments mismatch.  The change allows
cases in which CMake 2.6.2 silently ignored a mismatch to run as before
but with a warning.

Brad King bca1026250 ENH: Better error message for unclosed blocks
This centralizes construction of the error message for an unclosed
logical block (if, foreach, etc.).  We record the line at which each
block is opened so it can be reported in the error message.
2009-01-21 09:48:20 -05:00
Brad King b8f5a934ec ENH: Refactor logical block enforcement
This uses a stack of 'barriers' to efficiently divide function blockers
into groups corresponding to each input file.  It simplifies detection
of missing block close commands and factors it out of ReadListFile.
2009-01-21 09:48:00 -05:00
Brad King 2c81e5fb5c ENH: Refactor function blocker deletion
When a function blocker decides to remove itself we previously removed
it at every return point from the C++ scope in which its removal is
needed.  This teaches function blockers to transfer ownership of
themselves from cmMakefile to an automatic variable for deletion on
return.  Since this removes blockers before they replay their commands,
we no longer need to avoid running blockers on their own commands.

Brad King a541cac325 ENH: Improve response to bad if or elseif
Previously bad arguments to an if() or elseif() would cause some
subsequent statements in the corresponding block to execute.  This
teaches CMake to stop processing commands with a fatal error.  It also
provides context to bad elseif() error messages.
2009-01-20 14:35:22 -05:00
Brad King d602a3db85 BUG: Enforce matching policy PUSH/POP in all files
The documentation of cmake_policy PUSH and POP states that they must
always match.  Previously we enforced this only for the top scope of
each CMakeLists.txt file.  This enforces the requirement for all files.
2009-01-15 14:37:14 -05:00
Brad King 9551cafd69 BUG: Pop a function scope even on error
This uses an automatic variable to push and pop variable scope inside a
function call.  Previously if the function failed its scope would not be
popped.  This approach guarantees a balanced push/pop.
2009-01-14 15:14:06 -05:00
Brad King ed3bb743f4 ENH: Improve test property speed with a map
Previously we stored a vector of tests to preserve their order.
Property set/get operations would do a linear search for matching tests.
This uses a map to efficiently look up tests while keeping the original
order with a vector for test file generation.

Brad King 0ad5eb177b ENH: Return utility target after creation
After creating a utility target with AddUtilityCommand, return a pointer

needed.

Brad King 5f57efb417 BUG: Skip a command if its arguments fail to parse
If the arguments to a command fail to parse correctly due to a syntax
error, the command should not be invoked.  This avoids problems created
by processing of commands with bad arguments.  Even though the build
system will not be generated, the command may affect files on disk that
persist across CMake runs.

Brad King 33e865c041 ENH: Add unset() command.
This introduces the unset() command to make it easy to unset CMake
variables, environment variables, and CMake cache variables.  Previously
it was not even possible to unset ENV or CACHE variables (as in
completely remove them).  Changes based on patch from Philip Lowman.
See issue #7507.

Brad King b9b11903ab BUG: Fix computed directory property DEFINITIONS.
- The property tracks the value formed by add_definitions
    and remove_definitions command invocations.
  - The string should be maintained for use in returning for the
    DEFINITIONS property value.
  - It is no longer used for any other purpose.
  - The DEFINITIONS property was recently documented as deprecated.
  - See bug #7239.

Brad King 1381aab4b7 BUG: Remove check for files written by file(WRITE) being loaded.
- CMake 1.8 and below did not do the check but could get in
    infinite loops due to the local generate step.
  - CMake 2.0 added the check but failed to perform it in directories
    with no targets (see bug #678).
  - CMake 2.2 removed the local generate which fixed the problem but
    did not remove the check.
  - Between CMake 2.4 and 2.6.0rc6 the check was fixed to work even
    when no targets appear in a directory (see bug #6923).
  - Bottom line: the check is no longer needed.

Brad King e3666a1de5 ENH: Allow policy CMP0000 to be set explicitly
- Message for missing cmake_minimum_required is not issued
    until the end of processing the top CMakeLists.txt file
  - During processing a cmake_policy command may set behavior
  - OLD behavior is to silently ignore the problem
  - NEW behavior is to issue an error instead of a warning

Brad King f7f03347a6 ENH: Improve new error/warning message generation
- Add cmListFileBacktrace to record stack traces
  - Move main IssueMessage method to the cmake class instance
    (make the backtrace an explicit argument)
  - Change cmMakefile::IssueMessage to construct a backtrace
    and call the cmake instance version
  - Record a backtrace at the point a target is created
    (useful later for messages issued by generators)

- Add cmMakefile methods IssueError and IssueWarning
  - Maintain an explicit call stack in cmMakefile
  - Include context/call-stack info in messages
  - Nested errors now unwind the call stack
  - Use new mechanism for policy warnings and errors
  - Improve policy error message
  - Include cmExecutionStatus pointer in call stack
    so that errors deeper in the C++ stack under
    a command invocation will become errors for the
    command
