Kulla Christoph 048d1adb4e add_custom_command: Add DEPFILE option for Ninja
Provide a way for custom commands to inform the ninja build tool about
their implicit dependencies.  For now simply make use of the option an
error on other generators.

Closes: #15479

Brad King 180538c706 Source: Stabilize include order
Each source file has a logical first include file.  Include it in an
isolated block so that tools that sort includes do not move them.

Stephen Kelly 8174e5cd94 cmCustomCommand: Remove special member functions.
The compiler generated ones are fine.  The existing implementations
here are incorrect as they omit some members.

Brad King e15a7075b5 Add an option for explicit BYPRODUCTS of custom commands (#14963)
A common idiom in CMake-based build systems is to have custom commands
that generate files not listed explicitly as outputs so that these
files do not have to be newer than the inputs.  The file modification
times of such "byproducts" are updated only when their content changes.
Then other build rules can depend on the byproducts explicitly so that
their dependents rebuild when the content of the original byproducts
really does change.

This "undeclared byproduct" approach is necessary for Makefile, VS, and
Xcode build tools because if a byproduct were listed as an output of a
rule then the rule would always rerun when the input is newer than the
byproduct but the byproduct may never be updated.

Ninja solves this problem by offering a 'restat' feature to check
whether an output was really modified after running a rule and tracking
the fact that it is up to date separately from its timestamp.  However,
Ninja also stats all dependencies up front and will only restat files
that are listed as outputs of rules with the 'restat' option enabled.
Therefore an undeclared byproduct that does not exist at the start of
the build will be considered missing and the build will fail even if
other dependencies would cause the byproduct to be available before its
dependents build.

CMake works around this limitation by adding 'phony' build rules for
custom command dependencies in the build tree that do not have any
explicit specification of what produces them.  This is not optimal
because it prevents Ninja from reporting an error when an input to a
rule really is missing.  A better approach is to allow projects to
explicitly specify the byproducts of their custom commands so that no
phony rules are needed for them.  In order to work with the non-Ninja
generators, the byproducts must be known separately from the outputs.

Add a new "BYPRODUCTS" option to the add_custom_command and
add_custom_target commands to specify byproducts explicitly.  Teach the
Ninja generator to specify byproducts as outputs of the custom commands.
In the case of POST_BUILD, PRE_LINK, and PRE_BUILD events on targets
that link, the byproducts must be specified as outputs of the link rule
that runs the commands.  Activate 'restat' for such rules so that Ninja
knows it needs to check the byproducts, but not for link rules that have
no byproducts.

Peter Collingbourne fe5d6e8c0f Add USES_TERMINAL option for custom commands
Teach the add_custom_command and add_custom_target commands a new
USES_TERMINAL option.  Use it to tell the generator to give the command
direct access to the terminal if possible.

Ben Boeckel a08292059e genex: remove the need for backtraces
Rather than making dummy backtraces and passing them around, just make
backtraces optional.

Brad King d45e7f3461 cmCustomCommand: Return std::string from GetWorkingDirectory 2014-03-12 10:44:00 -04:00
Ben Boeckel 270eb96df0 strings: Remove cmStdString references
Casts from std::string -> cmStdString were high on the list of things
taking up time. Avoid such implicit casts across function calls by just
using std::string everywhere.

The comment that the symbol name is too long is no longer relevant since
modern debuggers alias the templates anyways and the size is a
non-issue since the underlying methods are generated since it's
inherited.

Brad King bfb7288f81 Record backtrace in cmCustomCommand
This will be used to report custom command errors to the user with a
backtrace pointing at the add_custom_command or add_custom_target call.

Brad King 96afb12087 Convert CMake to OSI-approved BSD License
This converts the CMake license to a pure 3-clause OSI-approved BSD
License.  We drop the previous license clause requiring modified
versions to be plainly marked.  We also update the CMake copyright to
cover the full development time range.

Brad King bed3ac8741 ENH: Remove SKIP_RULE_DEPENDS option from add_custom_command()
- Option was recently added but never released.
  - Custom commands no longer depend on build.make so we do
    not need the option.
  - Rule hashes now take care of rebuilding when rules change
    so the dependency is not needed.

Brad King 600e5e274e ENH: Add SKIP_RULE_DEPENDS option for add_custom_command()
- Allows make rules to be created with no dependencies.
  - Such rules will not re-run even if the commands themselves change.
  - Useful to create rules that run only if the output is missing.

Brad King d7a5d4c191 ENH: Added IMPLICIT_DEPENDS option to ADD_CUSTOM_COMMAND. It currently works only for Makefile generators. It allows a custom command to have implicit dependencies in the form of C or CXX sources. 2007-09-17 10:50:46 -04:00
Brad King 09289aadb6 ENH: Removed "Used" mark from custom commands. It is no longer needed or checked by any generators. 2007-05-28 11:18:15 -04:00
Alexander Neundorf 7f11536704 ENH: now target names can be used in add_custom_command() and
add_custom_target() as COMMAND, and cmake will recognize them and replace
them with the actual output path of these executables. Also the dependency
will be added automatically. Test included.
ENH: moved TraceVSDependencies() to the end of GlobalGenerator::Configure(),
so it is done now in one central place

Brad King 2dfa2ba888 ENH: Added APPEND option to ADD_CUSTOM_COMMAND to allow extra dependencies to be connected later. This is useful to create one rule and then have a macro add things to it later. This addresses bug#2151. 2006-10-04 15:24:26 -04:00
Brad King 9a1d4e92eb BUG: Fix/cleanup custom commands and custom targets. Make empty comment strings work. Fix ZERO_CHECK target always out of date for debugging.

Brad King d5719f22c1 ENH: Added support for multiple outputs generated by a single custom command. For Visual Studio generators the native tool provides support. For Xcode and Makefile generators a simple trick is used. The first output is considered primary and has the build rule attached. Other outputs simply depend on the first output with no build rule. During cmake_check_build_system CMake detects when a secondary output is missing and removes the primary output to make sure all outputs are regenerated. This approach always builds the custom command at the right time and only once even during parallel builds. 2006-04-11 11:06:19 -04:00

Brad King 39af9ee1e4 ENH: Updated implementation of custom commands. Multiple command lines are now supported effectively allowing entire scripts to be written. Also removed extra variable expansions and cleaned up passing of commands through to the generators.
