//
// The latter is done using the cache entries that record the
// dependencies of each library.
//
// The former is a more thorny issue, since it is not clear how to
// determine if two libraries listed on the link line refer to the a
// single library or not. For example, consider the link "libraries"
// /usr/lib/libtiff.so -ltiff
// Is this one library or two? The solution implemented here is the
// simplest (and probably the only practical) one: two libraries are
// the same if their "link strings" are identical. Thus, the two
// libraries above are considered distinct. This also means that for
// dependency analysis to be effective, the CMake user must specify
// libraries build by his project without using any linker flags or
// file extensions. That is,
// LINK_LIBRARIES( One Two )
// instead of
// LINK_LIBRARIES( -lOne ${binarypath}/libTwo.a )
// The former is probably what most users would do, but it never
// hurts to document the assumptions. :-) Therefore, in the analysis
// code, the "canonical name" of a library is simply its name as
// given to a LINK_LIBRARIES command.
2002-05-04 00:34:05 +04:00
//
// Also, we will leave the original link line intact; we will just add any
// dependencies that were missing.
//
// There is a problem with recursive external libraries
// (i.e. libraries with no dependency information that are
// recursively dependent). We must make sure that the we emit one of
// the libraries twice to satisfy the recursion, but we shouldn't
// emit it more times than necessary. In particular, we must make
// sure that handling this improbable case doesn't cost us when
// dealing with the common case of non-recursive libraries. The
// solution is to assume that the recursion is satisfied at one node
// of the dependency tree. To illustrate, assume libA and libB are
// extrenal and mutually dependent. Suppose libX depends on
// libA, and libY on libA and libX. Then
// TARGET_LINK_LIBRARIES( Y X A B A )
// TARGET_LINK_LIBRARIES( X A B A )
// TARGET_LINK_LIBRARIES( Exec Y )
// would result in "-lY -lX -lA -lB -lA". This is the correct way to
// specify the dependencies, since the mutual dependency of A and B
// is resolved *every time libA is specified*.
//
// Something like
// TARGET_LINK_LIBRARIES( Y X A B A )
// TARGET_LINK_LIBRARIES( X A B )
// TARGET_LINK_LIBRARIES( Exec Y )
// would result in "-lY -lX -lA -lB", and the mutual dependency
// information is lost. This is because in some case (Y), the mutual
// dependency of A and B is listed, while in another other case (X),
// it is not. Depending on which line actually emits A, the mutual
// dependency may or may not be on the final link line. We can't
// handle this pathalogical case cleanly without emitting extra
// libraries for the normal cases. Besides, the dependency
// information for X is wrong anyway: if we build an executable
// depending on X alone, we would not have the mutual dependency on
// A and B resolved.
//
// IMPROVEMENTS:
// -- The current algorithm will not always pick the "optimal" link line
// when recursive dependencies are present. It will instead break the
// cycles at an aribtrary point. The majority of projects won't have
// cyclic dependencies, so this is probably not a big deal. Note that
// the link line is always correct, just not necessary optimal.

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.

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.

Allow generator expressions in LINK_INTERFACE_LIBRARIES. The Config and IMPORTED_ variants may also contain generator expressions. If 'the implementation is the interface', then the result of evaluating the expressions at generate time is used to populate the IMPORTED_LINK_INTERFACE_LIBRARIES property. 1) In the case of non-static libraries, this is fine because the user still has the option to populate the LINK_INTERFACE_LIBRARIES with generator expressions if that is what is wanted. 2) In the case of static libraries, this prevents a footgun, enforcing that the interface and the implementation are really the same. Otherwise, the LINK_LIBRARIES could contain a generator expression which is evaluated with a different context at build time, and when used as an imported target. That would mean that the result of evaluating the INTERFACE_LINK_LIBRARIES property for a static library would not necessarily be the 'link implementation'. For example: add_library(libone STATIC libone.cpp) add_library(libtwo STATIC libtwo.cpp) add_library(libthree STATIC libthree.cpp) target_link_libraries(libtwo $<$<STREQUAL:$<TARGET_PROPERTY:TYPE>,STATIC_LIBRARY>:libone>) target_link_libraries(libthree libtwo) If the LINK_LIBRARIES content was simply copied to the IMPORTED_LINK_INTERFACE_LIBRARIES, then libthree links to libone, but executables linking to libthree will not link to libone. 3) As the 'implementation is the interface' concept is to be deprecated in the future anyway, this should be fine.

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.
