Stephen Kelly ca5d990f02 Help: Add a manual for compiler feature control.
Link to it from the documentation of related properties, variables
and commands.

Extend the cmake-developer(7) documentation with notes on
extending feature support for compilers.

Stephen Kelly b4d33f6484 Features: Add missing variable reference in docs. 2014-05-22 17:59:51 +02:00
Stephen Kelly e0890d03a4 Features: Extend concept to C language.
Add properties and variables corresponding to CXX equivalents.

Add features for c_function_prototypes (C90), c_restrict (C99),
c_variadic_macros (C99) and c_static_assert (C11). This feature
set can be extended later.

Add a <PREFIX>_RESTRICT symbol define to WriteCompilerDetectionHeader
to conditionally represent the c_restrict feature.

Stephen Kelly 205215fb8a cmTarget: Add CXX_STANDARD_REQUIRED to control decay. 2014-05-07 12:17:49 +02:00
Stephen Kelly 1df2116bfa Features: Decay language flag if requested is not available.
Use the highest standard compile flags available if requested language
version is too new.

This supports use-cases like

 set(CMAKE_CXX_STANDARD 14)

 # Compiled with -std=c++11 with GNU 4.7, which has no -std=c++14
 # or equivalent flag
 add_executable(main main.cpp)

This can be used in combination with preprocessor defines which
communicate the availability of certain language features for
optional use.

Stephen Kelly 5412deded1 cmTarget: Transitively evaluate compiler features.
Extend the interface of the target_compile_features command with
PUBLIC and INTERFACE keywords. Populate the INTERFACE_COMPILER_FEATURES
target property if they are set. Consume the INTERFACE_COMPILER_FEATURES
target property from linked dependent targets to determine the final
required compiler features and the compile flag, if needed.

Use the same pattern of origin-debugging which is used for other
build properties.

Stephen Kelly baff44345c cmTarget: Allow populating COMPILE_FEATURES using generator expressions.
Delay validation of the content as a feature if it contains a
generator expression. It will be checked again at generate-time
after evaluation.
2014-04-07 18:11:18 +02:00
Stephen Kelly 03355d6b5b cmTarget: Add COMPILE_FEATURES target property.
Use the contents of it to upgrade the CXX_STANDARD target property,
if appropriate.  This will have the effect of adding the -std=c++11
compile flag or other language specification on GNU when that is
needed for the feature.
2014-04-07 16:52:22 +02:00
Stephen Kelly 913394af24 cmTarget: Add CXX_STANDARD and CXX_EXTENSION target properties.
These are used to determine whether to add -std=c++11, -std=gnu++11
etc flags on the compile line.

Stephen Kelly 3676fb4963 cmTarget: Allow transitive evaluation of SOURCES property.
Extend the cmGeneratorExpressionDAGChecker with an interface
returning the name of the top target.  Use that to determine
when there is a DAG violation, as required by the RunCMake.Languages
tests.

Brad King fba51b096e MSVC: Add properties to configure compiler PDB files (#14762)
Since commit v2.8.12~437^2~2 (VS: Separate compiler and linker PDB files
2013-04-05) we no longer set /Fd with the PDB_NAME or PDB_OUTPUT_DIRECTORY
properties.  Those properties now exclusively handle linker PDB files.
Since STATIC libraries do not link their compiler PDB file becomes more
important.  Add new target properties "COMPILE_PDB_NAME[_<CONFIG>]" and
"COMPILE_PDB_OUTPUT_DIRECTORY[_<CONFIG>]" to specify the compiler PDB
file location and pass the value to the MSVC /Fd option.
2014-02-26 09:34:38 -05:00
Brad King aae5184c16 Help: Refactor PDB_NAME and PDB_OUTPUT_DIRECTORY docs
Move the note about VS 6 into the PDB_NOTE.txt common include file
and include it from the per-config properties too.  Also re-word
the note to clarify the separate compiler and linker flags involved
and state explicitly that compiler flags are not affected.

Alex Merry 635e96dde2 Help: Be clearer about which header files are considered for AUTOMOC
The old documentation stated that "all header files" were considered,
which was not true for any sensible definition of "all header files".

Stephen Kelly 98093c45db QtAutoUic: Add INTERFACE_AUTOUIC_OPTIONS target property.
Transitively consume the property from linked dependents.

Implement configuration-specific support by following the pattern
set out for compile definitions and includes in cmQtAutoGenerators.

Implement support for origin-tracking with CMAKE_DEBUG_TARGET_PROPERTIES.

This is motivated by the needs of KDE, which provides a separate
translation system based on gettext instead of the Qt linguist
translation system. The Qt uic tool provides command line options
for configuring the method used to translate text, and to add an
include directive to the generated file to provide the method.

 http://thread.gmane.org/gmane.comp.kde.devel.frameworks/7930/focus=7992

Implement the interface to provide the uic options as a usage-requirement
on the KI18n target, as designed for KDE.

Stephen Kelly 9c87d9cc3e Add automatic rcc invocation for Qt.

2013-10-24 12:30:41 +02:00
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.

Stephen Kelly ff6c401309 cmTarget: Add interface for compatible numeric properties
When using the boost MPL library, one can set a define to increase
the limit of how many variadic elements should be supported. The
default for BOOST_MPL_LIMIT_VECTOR_SIZE is 20:

 http://www.boost.org/doc/libs/1_36_0/libs/mpl/doc/refmanual/limit-vector-size.html

If the foo library requires that to be set to 30, and the independent
bar library requires it to be set to 40, consumers of both need to set
it to 40.

 add_library(foo INTERFACE)
 set_property(TARGET foo PROPERTY INTERFACE_boost_mpl_vector_size 30)
 set_property(TARGET foo PROPERTY COMPATIBLE_INTERFACE_NUMBER_MAX boost_mpl_vector_size)
 target_compile_definitions(foo INTERFACE BOOST_MPL_LIMIT_VECTOR_SIZE=$<TARGET_PROPERTY:boost_mpl_vector_size>)

 add_library(bar INTERFACE)
 set_property(TARGET bar PROPERTY INTERFACE_boost_mpl_vector_size 40)
 # Technically the next two lines are redundant, but as foo and bar are
 # independent, they both set these interfaces.
 set_property(TARGET bar PROPERTY COMPATIBLE_INTERFACE_NUMBER_MAX boost_mpl_vector_size)
 target_compile_definitions(bar INTERFACE BOOST_MPL_LIMIT_VECTOR_SIZE=$<TARGET_PROPERTY:boost_mpl_vector_size>)

 add_executable(user)
 target_link_libraries(user foo bar)

Because the TARGET_PROPERTY reads the boost_mpl_vector_size property
from the HEAD of the dependency graph (the user target), and because
that property appears in the COMPATIBLE_INTERFACE_NUMBER_MAX of
the dependencies of the user target, the maximum value for it is
chosen for the compile definition, ie, 40.

There are also use-cases for choosing the minimum value of a number.
In Qt, deprecated API can be disabled by version. Setting the
definition QT_DISABLE_DEPRECATED_BEFORE=0 disables no deprecated
API. Setting it to 0x501000 disables API which was deprecated before
Qt 5.1 etc.

If two dependencies require the use of API which was deprecated in
different Qt versions, then COMPATIBLE_INTERFACE_NUMBER_MIN can be
used to ensure that both can compile.
