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.
Otherwise, in the string case, we would get a null pointer instead
of the implied empty string. That will become relevant when the
comparison result is used.

Other warnings for the same policy already have similar output since
commit 81d2793e (Add differing target property content to policy CMP0022
warning, 2013-09-11).
The cmRST implementation and the list of capabilities documented in the
cmake-developer.7 manual must be kept in sync. Add a note to each file
to reference the other.
Add cmCommand::Disallowed helper to check the setting of a policy that
disallows the command. Add a RunCMake.DisallowedCommands test
placeholder. Add a Help/policy/DISALLOWED_COMMAND.txt file for
inclusion by each policy document to avoid duplication of the common
text.
Teach cmRST to recognize non-markup lines ending in '::' followed by a
blank line as starting a literal block. Record the whole block as if it
were a literal block directive and print it just like a code block.
Extend the CMakeLib.testRST test to cover such cases.
Move the ProcessDirectiveParsedLiteral and ProcessDirectiveCodeBlock
method internals into an OutputMarkupLines helper. Pass through it a
new "inlineMarkup" parameter and teach OutputLine to understand it.
When false, do not process inline markup. Extend the CMakeLib.testRST
test to cover the two cases.
CMake/Source/cmGeneratorExpressionParser.cxx: In member function ‘void cmGeneratorExpressionParser::ParseGeneratorExpression(std::vector<cmGeneratorExpressionEvaluator*>&)’:
CMake/Source/cmGeneratorExpressionParser.cxx:116:55: warning: conversion to ‘unsigned int’ from ‘long int’ may alter its value [-Wconversion]
CMake/Source/cmGeneratorExpressionParser.cxx:240:39: warning: conversion to ‘int’ from ‘long int’ may alter its value [-Wconversion]
Add a string(CONCAT) command to simply concatenate input arguments
together. This will be useful for combining strings from different
quoting syntaxes. Add a RunCMake.string test covering these cases.
Teach the Xcode generator to set 'lastKnownFileType' to be 'folder' for
file references that are directories. If you set 'explicitFileType' to
'sourcecode', then Xcode cannot browse the directory.
Introduce a policy to control the behavior.
The AliasTargets unit test already tests that using a
double-semicolon in the name is not an error. Change the ExportImport
test to use a namespace with a double-semicolon too.
The result is that the depends of the target are created.
So,
add_library(somelib foo.cpp)
add_library(anotherlib EXCLUDE_FROM_ALL foo.cpp)
add_library(extra EXCLUDE_FROM_ALL foo.cpp)
target_link_libraries(anotherlib extra)
add_library(iface INTERFACE)
target_link_libraries(iface INTERFACE anotherlib)
Executing 'make iface' will result in the anotherlib and extra targets
being made.
Adding a regular executable to the INTERFACE of an INTERFACE_LIBRARY
will not result in the executable being built with 'make iface' because
of the logic in cmComputeTargetDepends::AddTargetDepend.
So far, this is implemented only for the Makefile generator. Other
generators will follow if this feature is possible for them.
Make INTERFACE_LIBRARY targets part of the all target by default.
Test this by building the all target and making the expected library
EXCLUDE_FROM_ALL.
Teach the VS 7-9 generators to honor the
VS_DOTNET_TARGET_FRAMEWORK_VERSION
target property. This was already done for VS >= 10 by commit cfe6300a
(VS: Add support for .NET target framework version, 2013-06-14).
