Brad King 60eb396f10 Export: Escape exported property values when writing CMake language files
When writing export files, correctly encode property values that contain
characters special to the CMake language parser.  We must ensure that
they parse correctly when loaded on the consuming side.

Brad King f30022eb07 install: Allow generator expressions in TARGETS DESTINATION (#14317)
This will allow per-config destinations for targets in EXPORT sets.
Using multiple install(TARGETS) with separate CONFIGURATIONS is
rejected as a target appearing more than once in an export set.
Now instead one can write

 install(TARGETS foo EXPORT exp DESTINATION lib/$<CONFIG>)

to get a single logical membership of the target in the export set
while still having a per-config destination.

Stephen Kelly 6da65b3907 Allow export of targets with INTERFACE_SOURCES.
Use the same rules for paths in source and binary dirs in
installed INTERFACE_SOURCES as are used for
INTERFACE_INCLUDE_DIRECTORIES.

Brad King dd089e08b5 install: Allow absolute EXPORT destination with relative targets (#15258)
When install(EXPORT) is given an absolute destination we cannot compute
the install prefix relative to the installed export file location.
Previously we disallowed installation of targets in such exports with a
relative destination, but did not enforce this for target property
values besides the location of the main target file.  This could lead to
broken installations when the EXPORT is installed to an absolute path
but usage requirements are specified relative to the install prefix.

Since an EXPORT installed to an absolute destination cannot be relocated
we can just hard-code the value of CMAKE_INSTALL_PREFIX as the base for
relative paths.  This will allow absolute install(EXPORT) destinations
to work with relative destinations for targets and usage requirements.

Extend the ExportImport test with a case covering this behavior.

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 cbe7e8fae4 export: Implement EXPORT subcommand (#9822)
Teach the export command to handle export sets defined by invocations

Stephen Kelly 7a3e45b9d4 Export: Prefix relative items with genexes in INSTALL_INTERFACE.
Code such as

 target_include_directories(foo INTERFACE
   $<INSTALL_INTERFACE:include$<FOO>>
 )

should be treated as a relative directory, despite the genex, after
the INSTALL_INTERFACE is stripped away.

Previously, this would generate a relative directory on export, which
would be an error on import, so no policy is needed.

Stephen Kelly f088a32450 Export: Process INSTALL_INTERFACE in INCLUDES DESTINATION.

Stephen Kelly 9eedc850eb Export: Process relative includes after genex evaluation.
In code such as

 install(TARGETS ...

 )

the generator expressions are evaluated at generate-time. Delay
determining whether each entry is a relative path until after
the generator expressions are evaluated. Such relative paths
are based relative to the CMAKE_INSTALL_PREFIX.

Stephen Kelly f063c45589 Consider targets with double colons to be IMPORTED or ALIAS targets.
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.

Stephen Kelly 6f98f4ac92 Genex: Fix processing multiple include directories for relative paths
Re-insert the semicolon which was removed during splitting.

Commit d777b8e7 (Genex: Allow relative paths in INSTALL_INTERFACE.,
2013-07-25) introduced the prefixItems method to allow relative paths
in the argument of the INSTALL_INTERFACE expression. That method was
buggy in that it did not re-introduce the semicolon separator in
the result.

This bug also affects paths which are already absolute in user code.

new feature is used with a target which has no

without unintended cross-pollution of export sets.

Brad King 295a42c96c Fix ExportImport test cmp0022NEW build on Watcom
The test uses generate_export_header(cmp0022OLD ...) to generate the
cmp0022_export.h header used by both cmp0022OLD and cmp0022NEW.  In
the latter the _EXPORTS symbol does not match what the header expects
so the library does not export anything.  The Watcom linker does not
like to create shared libraries that do not export any symbols.

Fix this by setting the DEFINE_SYMBOL property on cmp0022NEW to match
that of cmp0022OLD as the header expects.

Stephen Kelly 574fec97fd Export: Generate INTERFACE_LINK_LIBRARIES property on targets.
This property is generated only for targets which have recorded
policy CMP0022 as NEW, and a compatibility mode is added to
additionally export the old interfaces in that case too.

If the old interfaces are not exported, the generated export files
require CMake 2.8.12. Because the unit tests use a version which
is not yet called 2.8.12, temporarily require a lower version.

Stephen Kelly 4f7ceb56d1 Test non-IMPORTED libraries in the INTERFACE of IMPORTED libraries.
If a non-IMPORTED library is added to the INTERFACE_LINK_LIBRARIES
of a IMPORTED target, the non-IMPORTED target needs to become a
target dependency and link dependency of the consuming target.

This is already the case since commit 30962029 (Make targets depend
on the link interface of their dependees, 2012-12-26), and fixed in
the parent commit, so test that it works.

Check that source and binary directories are not part of the

This is limited to directories which do not contain generator
expressions to evaluate. Such paths can only be checked at time
of use of the imported target, which will be done in a follow up
patch.

Stephen Kelly 7a619fa6fb Fix cmGeneratorExpression::Preprocess for interleaved inputs.
We can't find both preprocessing expressions at once, because then
the BUILD_INTERFACE will always be favored if both are present, even
if INSTALL_INTERFACE appears first.

This was affecting the behavior of install(EXPORT) because the
INTERFACE_INCLUDE_DIRECTORIES contained entries like

 /foo/include;$<INSTALL_INTERFACE:/bar/include>

As the INSTALL_INTERFACE always evaluates to '0', it always needs
to be preprocessed properly.

Stephen Kelly 77cecb778f Add includes and compile definitions with target_link_libraries.
This establishes that linking is used to propagate usage-requirements

would introduce confusion due to multiple commands which differ only in
a subtle way.
