Robert Maynard 6dbd4a5f17 cmMakefile: Refactor AddCMakeDependFile and AddCMakeOutputFile.
AddCMakeDependFile and AddCMakeOutputFile both store as std::string
and all calling sites use std::string. So instead of creating more
temporary objects, lets just use std::strings.

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.
2013-01-21 09:12:22 +01:00
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
debugging the INCLUDE_DIRECTORIES property.

Stephen Kelly 18a3195ad5 Keep track of INCLUDE_DIRECTORIES as a vector of structs.
The struct can keep track of where the include came from, which gives
us proper backtraces.

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.

Brad King f9b758e91a Cleanup custom command .rule file internal handling
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
instead of trusting the file extension.

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
the NEW behavior of the policy breaks a valid use case:

  # CMakeLists.txt
  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.

See issue #9008.

Brad King ee2b446c95 Create CMake Policy CMP0015 to fix set(CACHE)
The set(CACHE) and option() commands should always expose the cache
value.  Previously we failed to expose the value when it was already set
if a local variable definition hid it.  When set to NEW, this policy
tells the commands to always remove the local variable definition to
expose the cache value.  See issue #9008.

Brad King afbe088309 Remove barely-used cmMakefile::AddCacheDefinition
The boolean overload of this method was used only to implement option().

fallen behind on changes (it was not removing the local definition
instead of setting it).

Brad King 80c947b397 No /fast targets in try_compile project mode
The try_compile command builds the cmTryCompileExec executable using the

time since dependencies are not needed.  However, in project mode the
command builds an entire source tree that may have dependencies.
Therefore we can use the /fast target approach only in one-source mode.

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
directories whose build files would then conflict.  At first this was
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.
See issue #9173.

Brad King c332e0bf3c ENH: Isolate policy changes in included scripts

load, with a NO_POLICY_SCOPE option to disable the behavior.  This also
creates CMake Policy CMP0011 to provide compatibility.  See issue #8192.

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 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.

  - 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 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)

    and call the cmake instance version
  - Record a backtrace at the point a target is created
    (useful later for messages issued by generators)

Brad King 680104a490 ENH: New format for warning and error messages
- 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

Brad King 5594ad4885 ENH: Updated exporting and importing of targets to support libraries and configurations.
- Created cmExportFileGenerator hierarchy to implement export file generation
  - Installed exports use per-config import files loaded by a central one.
  - Include soname of shared libraries in import information
  - Renamed PREFIX to NAMESPACE in INSTALL(EXPORT) and EXPORT() commands
  - Move addition of CMAKE_INSTALL_PREFIX to destinations to install generators
  - Import files compute the installation prefix relative to their location when loaded
  - Add mapping of importer configurations to importee configurations
  - Rename IMPORT targets to IMPORTED targets to distinguish from windows import libraries
  - Scope IMPORTED targets within directories to isolate them
  - Place all properties created by import files in the IMPORTED namespace
  - Document INSTALL(EXPORT) and EXPORT() commands.
  - Document IMPORTED signature of add_executable and add_library
  - Enable finding of imported targets in cmComputeLinkDepends

Brad King 35936433e1 ENH: Merging changes from branch CMake-SourceFile2-b between tags
CMake-SourceFile2-bp and CMake-SourceFile2-b-mp1 to trunk.  This
commit is surrounded by tags CMake-SourceFile2-b-mp1-pre and
CMake-SourceFile2-b-mp1-post on the trunk.

The changes re-implement cmSourceFile and the use of it to allow
instances to be created much earlier.  The use of cmSourceFileLocation
allows locating a source file referenced by a user to be much simpler
and more robust.  The two SetName methods are no longer needed so some
duplicate code has been removed.  The strange "SourceName" stuff is
gone.  Code that created cmSourceFile instances on the stack and then
sent them to cmMakefile::AddSource has been simplified and converted
to getting cmSourceFile instances from cmMakefile.  The CPluginAPI has
preserved the old API through a compatibility interface.

Source lists are gone.  Targets now get real instances of cmSourceFile
right away instead of storing a list of strings until the final pass.

TraceVSDependencies has been re-written to avoid the use of
SourceName.  It is now called TraceDependencies since it is not just
for VS.  It is now implemented with a helper object which makes the
code simpler.

Alexander Neundorf 9d4f3a0686 STYLE: remove duplicate non-const accessors GetLocalGenerator(int) and
GetLocaGenerators(cmLocalGenerators) from cmGlobalGenerator(). Now there is
one const accessor which is even faster since it returns a reference
(instead of copying a vector)
-more const to ensure that this the returned local generators don't actually
get modified
-removed duplicated code in GetCTestCommand() and GetCPackCommand()
-added some const accessors
