Teach the compiler identification preprocessor tests to report when
Clang simulates MSVC, and what version. If not MSVC, assume GNU.
Teach compiler information modules Clang-(C|CXX) to recognize when Clang
simulates MSVC and skip loading the GNU information.
Teach the Windows-MSVC platform information to recognize when it is
loaded as the simulated compiler and use that version information
instead of the real compiler's (different) version scheme.
Add platform modules Windows-Clang-(C|CXX) and support module
Windows-Clang to load either Windows-MSVC or Windows-GNU and wrap
the corresponding information macros.
Some compilers try to simulate other compilers as a drop-in replacement
supporting all the same command-line options and predefined preprocessor
macros. In such cases it will be useful to have CMake load the compiler
information files for the simulated compiler instead of duplicating the
information. Teach CMakeDetermineCompilerId to extract the simulated
compiler id and version when the compiler id detection provides it.

The subsystem must be set to WINDWOSCE for some SDKs to link an
executable. Set it to 9 for VS2005 and to 8 for VS2008, since the
value differs between the different Visual Studio versions.
In commit bd827f98 (Use COFF file header header for architecture
detection, 2013-08-05) the MSVC_<lang>_ARCHITECTURE_ID value computed by
CMakeDetermineCompilerId.cmake changed for WinCE architectures to be the
exact architecture read from the PE header. Fix platform preprocessor
definitions in Modules/Platform/Windows-MSVC.cmake to correspond to the
architecture family (ARM or SHx) instead of the specific architecture.
In commit 8fcf0ab0 (Add support for new Windows CE compiler, 2013-08-04)
we made corelibc conditional on the MSVC version, but the version value

When FindHDF5 was first added in commit e6734068 (Add HDF5 find
module..., 2009-08-24) it contained a workaround for a bug in
SelectLibraryConfigurations that did not transform lists correctly.
That bug was fixed by commit 5797512c (SelectLibraryConfiguration:
generate correct output when input vars are lists, 2012-07-28). Then
refactoring in commit 04d4dc33 (SelectLibraryConfigurations: Use
-NOTFOUND instead of copying the vars, 2013-07-08) changed undocumented
behavior on which the original workaround relied. The result puts
entries like HDF5_hdf5_LIBRARY_DEBUG-NOTFOUND in HDF5_LIBRARIES.
Fix this by dropping the original workaround since the underlying issue
has been fixed anyway. Use the HDF5_${LIB}_LIBRARY selected by the call
to select_library_configurations directly.
In commit 2a797539 (FindPNG: improve library detection, 2013-07-27) we
split the search for PNG into separate PNG_LIBRARY_DEBUG and
PNG_LIBRARY_RELEASE variables. However, if a project or user sets the
old PNG_LIBRARY value we must honor it instead of searching.
While at it, mark PNG_LIBRARY_RELEASE and PNG_LIBRARY_DEBUG as advanced
and remove a stray debug message.
CMake's intended interface for linking to explicit object files (marked
with EXTERNAL_OBJECT) is that only those listed as target sources should
be linked. Drop FindCUDA's attempt to hide the .obj files from VS IDE
project files, which depends on VS-version-specific behavior of linking
custom command outputs that happen to be named "*.obj". CMake puts
external object files in a dedicated source group anyway.
In commit fb9f73de (MSVC: Invoke 'link' directly for executables,
2013-04-08) we forgot to remove the /link option handling added by
commit e31df039 (Ninja: move <OBJECTS> in front of the first linker
option, 2012-09-27) to the Platform/Windows-MSVC module. Drop it now.
When compiling the 64 bit version of wxWidgets using nmake the library

When the VS IDE build output setting
Tools -> Options -> Projects and Solutions ->
Build and Run -> MSBuild project output verbosity
is set to "Diagnostic" the build output contains a " (TaskId:###)"
suffix on the CMAKE_<lang>_COMPILER= line used to extract the compiler
executable location. Strip this suffix before checking that the
reported location exists.
Follow-up to commit 4a015f77 (OpenBSD: Add paths for Tcl/Tk 8.4/8.5,

of which are already using version 8.6 of Tcl/Tk.
After building the test binary tell find_program to search for it with
the ${CMAKE_EXECUTABLE_SUFFIX} so that the .exe can be found. Since
find_program is normally used to locate host tools while cross-compiling
it needs this hint to find the target binary.

95f78e0 OS X: Search for SDK based on deployment target (#14324)
Since we do not need the information about the target architecture
we can use the PlatformName only to specify the this information.
This also removes setting of the MSVC_*_ARCHITECTURE_ID variable
which is not required, because this variable gets set by the
compiler detection code in CMAKE_DETERMINE_COMPILER_ID_CHECK().
The Microsoft linker is intelligent enough to detect the target
machine type depending on the input files. This allows us to
get the target architecture from the compiler instead of
maintaining the mapping to the platform name.
When available, use CMAKE_OSX_DEPLOYMENT_TARGET instead of the host OS X
version to select the default SDK. This makes sense because one should
use the SDK matching the deployment target.

This fixes a regression introduced by commit b8af46cb (FindQt4: Don't
fail if certain Qt modules are unavailable., 2013-05-23)
The _FOUND variable is set by the _QT4_ADJUST_LIB_VARS macro, so
invoke that unconditionally, and guard only the set_property calls,
as described in the original bug report (#14165).

If one of the libraries (_DEBUG or _RELEASE) is not set, the value is
set to the value of the other one. FindQt4, from which the macro is
extracted, sets the values to XXX_LIBRARY_{DEBUG,RELEASE}-NOTFOUND
instead. In both cases the XXX_LIBRARY is correct, but using NOTFOUND
makes it easier to understand which one is missing.
Update Tests/CMakeOnly/SelectLibraryConfigurations with the new logic.
Ubuntu install the CUDA libraries into a location that is different
than the default location provided by the NVidia installer. So we
teach the FindCUDA package to also find the Ubuntu install location.
WiX provides a lot of functionality for installers that cannot be
supported (easily) in the default WIX.template.in file.
For most users, the default template should be fine. However if users
want to produce merge modules, include custom actions, etc, this new
option allows for a hook into how the wxs is produced.
If one installs MinGW using the Code::Blocks IDE installer it goes to a
path like "c:\Program Files\CodeBlocks\MinGW", not "c:\MinGW". Use the
CodeBlocks registry entry to get the location.

In CMakeDetermineCompilerABI we use try_compile with the COPY_FILE
option to get a copy of the compiled binary used to detect the ABI
information. We already tolerate the case when compilation fails.
However, when compilation appears to succeed but does not produce the
expected executable the try_compile command immediately reports an error
because the COPY_FILE fails.
Tolerate COPY_FILE failure without stopping the overall configuration
process by using the try_compile COPY_FILE_ERROR option to capture the
error message. Log the full error to CMakeError.log and simply report
failure to detect the ABI as if compilation had failed.
Teach the RunCMake.Configure test to cover this case and verify that the
messages show up as expected both in stdout and in CMakeError.log.
The VS IDE sets the environment variable VS_UNICODE_OUTPUT when
executing build rules in order to tell MS tools to report output through
a back door instead of through stdout/stderr. Unset this variable so
that CMake can capture or properly redirect all output from processes it
runs even when running inside a VS IDE build environment.
This generalizes the special cases fixed by commit 80d045b0 (When
GetPrerequisites.cmake runs dumpbin while running inside the VS IDE...,
2008-05-01) and commit 44aff73d (ExternalProject: Avoid bleed-through
output when logging, 2011-01-06), so drop special handling of
VS_UNICODE_OUTPUT in those instances.
The command line string passed to javac can exceed the 8191-character
limit on Windows when there are a large number of files to compile.
To avoid this, the list of sources is written to a file which is then
passed to javac as an argfile. Spaces in paths are dealt with by
enclosing each file in quotes, and separating files with a newline.
The linker flags for setting the compatibility and current versions of
libraries on Darwin are set for the supported Fortran compilers.
Set CMAKE_Fortran_CREATE_SHARED_LIBRARY for the NAG Fortran compiler to
have no space after <SONAME_FLAG> so the NAG compiler can parse the
argument correctly.
SelectLibraryConfigurations module currently cache and mark as advanced
the variable ${basename}_LIBRARY.
${basename}_LIBRARY_RELEASE and ${basename}_LIBRARY_DEBUG are usually
cached, because they often come from find_library().
${basename}_LIBRARY on the other hand is always of type
"optimized;${${basename}_LIBRARY_RELEASE};debug;${${basename}_LIBRARY_DEBUG}"
or just "${basename}_LIBRARY_RELEASE" or "${basename}_LIBRARY_DEBUG" if
only one version of the library is not found, if both have the same
value, or if configuration types are not supported.
Caching and marking as advanced just ${basename}_LIBRARY_RELEASE and
${basename}_LIBRARY_DEBUG is enough, just by modifying these two
variables, the user has enough control on finding the library, and
having 3 variables is redundant and confusing.
We support multiple commands per external project step by using
the COMMAND keyword. Document this behavior and show an example.
While at it, document that shell operators and current working
directory behavior is not defined.
In CMakeTestFortranCompiler we build a test program using a Fortran 90
construct to check whether the compiler supports the language. Some
compilers have options to require explicit variable types. Fix the test
program to use an explicit variable type so it passes under such a

For clang, this allows passing -target <triple> to the compiler, and
for qcc, -V<arch> using toolchain files containing something like
set(triple arm-linux-gnueabihf)
set(CMAKE_C_COMPILER "/usr/bin/clang")
set(CMAKE_C_COMPILER_TARGET ${triple})
set(CMAKE_CXX_COMPILER "/usr/bin/clang++")
set(CMAKE_CXX_COMPILER_TARGET ${triple})
or
set(arch gcc_ntoarmv7le)
set(CMAKE_C_COMPILER /opt/qnx650/host/linux/x86/usr/bin/qcc)
set(CMAKE_C_COMPILER_TARGET ${arch})
set(CMAKE_CXX_COMPILER /opt/qnx650/host/linux/x86/usr/bin/QCC)
set(CMAKE_CXX_COMPILER_TARGET ${arch})
Both clang and qcc are inherently cross compiler( driver)s.
As CMAKE_ROOT_FIND_PATH can be a list, a new CMAKE_SYSROOT is
introduced, which is never a list.
The contents of this variable is passed to supporting compilers
as --sysroot. It is also accounted for when processing implicit
link directories reported by the compiler, and when generating
RPATH information.
dc1d025 OS X: Add test for rpaths on Mac.
8576b3f OS X: Add support for @rpath in export files.
00d71bd Xcode: Add rpath support in Xcode generator.
94e7fef OS X: Add RPATH support for Mac.
RPATH support is activated on targets that have the MACOSX_RPATH
property turned on.
For install time, it is also useful to set INSTALL_RPATH to help
find dependent libraries with an @rpath in their install name.
Also adding detection of rpath conflicts when using frameworks.
That will allow things like this:
find_package(Qt4)
qt4_generate_moc(myfile.h moc_myfile.cpp TARGET foo) # Note, foo target doesn't
# exist until below.
add_library(foo ...)
The qt4_generate_moc call would use the INCLUDE_DIRECTORIES from
the foo target using generator expressions. Currently it reads
the INCLUDE_DIRECTORIES directory property, meaning that include_directories()
is required.
Support for the TARGET is also added to qt4_wrap_cpp, but not qt4_automoc,
as that is deprecated in favor of the AUTOMOC target property.
The moc tool reports failure if the Q_INTERFACES macro is used with
an argument which has not appeared with Q_DECLARE_INTERFACE, so that is
the basis of the unit test.
The command line arguments are now always written to a file, which is
passed to moc as the @atfile. This was already the case on Windows, but
now it is used everywhere. The reason for that is that it is not currently
possible to expand the list of includes from a target directly in
a add_custom_command invokation (though that may become possible in the
future). There is not a big disadvantage to using the file anyway on
unix, so having one code path instead of two is also a motivation.
This corresponds to the g++ and clang++
option -fvisibility-inlines-hidden on linux. On Windows with MinGW,
this corresponds to -fno-keep-inline-dllexport. That option is
not supported by clang currently.
This is initialized by CMAKE_<LANG>_VISIBILITY_PRESET. The target
property is used as the operand to the -fvisibility= compile option
with GNU compilers and clang.
In commit 5b9149e0 (FindBoost: Overhaul caching and search repeat
behavior, 2012-09-24) we refactored the internal library search to use a
_Boost_FIND_LIBRARY macro to wrap around find_library calls. However,
CMake macros re-process escape sequences when evaluating calls inside
the macro after substituting placeholders (a historical bug). In order
to avoid escape sequences, convert backslashes to forward slashes before
passing arguments to the _Boost_FIND_LIBRARY macro.
The line
set( ${basename}_LIBRARY )
removes the normal variable, but if the corresponding cached variable is
present then line
list( APPEND ${basename}_LIBRARY optimized "${_libname}" )
uses that and fails. Replace the original line with
set( ${basename}_LIBRARY "" )
to set the normal variable to empty instead of unsetting it.
In Qt 5.1, Qt5::Core has a INTERFACE_QT_MAJOR_VERSION property
of '5', and since CMake 2.8.11, Qt4::QtCore has an
INTERFACE_QT_MAJOR_VERSION of '4'. This was introduced in
commit 4aa10cd6 (FindQt4: Set the INTERFACE_QT_MAJOR_VERSION for
Qt4::QtCore, 2013-03-16), to produce an error if Qt 4 and Qt 5
are erroneously used by the same target. This can also be used
however to determine the Qt major version, and therefore the
particular moc executable to use during automoc steps. This means
that targets in a single buildsystem can use a selection of Qt 4
and Qt 5, and still take advantage of the CMAKE_AUTOMOC feature
without conflicting.
The ExternalData_LINK_CONTENT option tells ExternalData to convert real
data files it finds into content links and to "stage" the original
content in a ".ExternalData_<algo>_<hash>" file. However, after a data
object has been staged it is possible that a user-provided pattern in
the "REGEX:" option will later match the staged object file. We must
not process staged object files even when a user pattern matches them.
Fix the implementation to not match a staged object file as a normal
data file for conversion. Extend the RunCMake.ExternalData test to
cover this case.
Modify FindProtobuf.cmake to find the pthread library on UNIX platforms,
and to add the same to PROTOBUF_LIBRARIES, as this is a link dependency
of libraries using the protobuf headers.
The variables in this module are used to configure a header file
with defines whose name depends on the name of the target.
As valid names of targets may be invalid for use as defines, convert
the names of the defines used to C identifiers first. This is already
done in C++ code for the DEFINE_SYMBOL property.
This is not as simple as ensuring that the BASE_NAME is a C identifier,
because most of the define names are configurable, and because use of
a BASE_NAME which is not a C identifier, such as 4square can become a
C identifier by specifying a prefix in the generate_export_header
macro.
The significant issue with MODULEs is that on Windows, the exported
symbols must be dllexported and they are not imported.
In other export macro implementations this is done by defining an
export macro outside of any ifdef which depends on definitions set
on the command line. However, with cmake we already expect the
DEFINE_SYMBOL to be defined, so the regular EXPORT macro can be
used by such plugins.
Teach CMakeParseImplicitLinkInfo to convert the CMAKE_LINKER file name
to a regular expression that matches only the original name. Escape
special characters like '+' so they are not treated as regex syntax.

with many special characters.

Commit dac78148 (...makes the mingw cross compiler work out of the
box..., 2007-08-02) added to CMAKE_SYSTEM_PROGRAM_PATH and
CMAKE_SYSTEM_LIBRARY_PATH paths like "/bin" and "/lib" with no Windows
drive letter so that cross-compiling to Windows from Linux would search
these paths under CMAKE_FIND_ROOT_PATH. Later commit 2a782880 (...use
CMAKE_SYSTEM_PREFIX_PATH when possible, 2008-01-16) generalized this
approach by instead adding "/" to CMAKE_SYSTEM_PREFIX_PATH.
Both commits assumed that the paths would never match anything on
Windows hosts without a drive letter. However, Windows evaluates these
paths relative to the current working drive letter so find_* commands
may report paths like "/lib/..." when paths like "c:/lib/..." exist on
what happens to be current drive. Such drive-less paths are not
reliable when the working drive changes, so we should not use them.
Fix WindowsPaths.cmake to add '/' to CMAKE_SYSTEM_PREFIX_PATH only when
cross-compiling to Windows from a non-Windows host. This will avoid
searching and finding local paths without a drive letter on Windows.
Set the locale to C while running the compiler for these checks because
we match the resulting warning messages in English only.

Use of the mis-spelled variable name 'CMAKE_CROSS_COMPILING' was
introduced by commit 4b793ad1 (FindOpenSSL: find cross-compiled OpenSSL
from MinGW, 2012-07-23). Fix the spelling.
Update the CMAKE_<LANG>_LINK_EXECUTABLE rule variable to invoke the
linker directly instead of through the compiler. We already do this
for DLL linking with CMAKE_<LANG>_CREATE_SHARED_LIBRARY.
This also works around a VS 6 cl bug. While invoking the link tool
internally it fails to correctly quote flags like /pdb:... with spaces
in the value.
The MS tools create two types of PDB files as explained here:
http://msdn.microsoft.com/en-us/library/yd4f8bd1%28v=vs.71%29.aspxhttp://msdn.microsoft.com/en-us/library/yd4f8bd1%28v=vs.80%29.aspxhttp://msdn.microsoft.com/en-us/library/yd4f8bd1%28v=vs.90%29.aspxhttp://msdn.microsoft.com/en-us/library/yd4f8bd1%28v=vs.100%29.aspx
One is created by the compiler (/Fd) and the other by the linker (/pdb).
The two options should not specify the same file. Split them up.
In the VS IDE generators, simply drop ProgramDataBaseFileName to
take the VS default "/Fd$(IntDir)vc$(PlatformToolsetVersion).pdb".
In the Makefile generators, set "/Fd" on the compile line to be
the directory containing object files (with a trailing slash the
compiler will add the "vc$(PlatformToolsetVersion).pdb" filename
automatically). Drop the /Fd option from the exe link command
line and add "/pdb" instead (already done for dll linking).
Update these rules for both MSVC and Intel tools.
Drop support for PDB_OUTPUT_DIRECTORY and PDB_NAME in STATIC
libraries because the generated .pdb files are only from /Fd
and not real linker-generated .pdb files. Update documentation to
clarify that the PDB_* properties are only for linker .pdb files.
This regresses the PDBDirectoryAndName test for STATIC libraries.
Since it is not clear at this time what should be done for STATIC
library .pdb files, comment out the relevant portion of the test
and leave a TODO comment.
This fixes bug #0013609, and is a possible solution to #0012864 as well.
The later will be completely fixed in another way. Both approaches
needs to be implemented because the current one is more automatic.

In commit 0c727b90 (install(EXPORT): Force absolute paths for usr-move,
2013-03-08) and commit d4774140 (configure_package_config_file: force
absolute paths for usr-move, 2013-01-24) we supported Linux
distributions implementing the "/usr move" by assuming that installation
to (/usr)?/lib(64)? represents a non-relocatable system package.
When cross-compiling one may prepare a package for installation into a
system location on a target machine but install the package files on the
*host* machine inside another path for use with CMAKE_FIND_ROOT_PATH.
In this case the package development files must still be relocatable.
Handle "/usr move" with a new approach that works with relocatable
files. Teach configure_package_config_file and install(EXPORT) to
generate special logic in a package configuration file or targets file
for installation under (/usr)?/lib(64)?. Teach the file to recognize
when it is loaded through a symlink that refers to the same realpath as
its original install destination. In such a case, use the original
install prefix. Otherwise, compute the prefix relative to the current
file location to make it relocatable.
CPACK_RPM_USER_BINARY_SPECFILE can now be specified on a per-component
basis using CPACK_RPM_<componentName>_USER_BINARY_SPECFILE.
Inspired-By: Theodore Papadopoulo with its patch proposal.
Using XXX as name of the package is ambiguous, since it can be
interpreted as "ALLUPPERCASE" and also as "ExactCase (if the name
is already ALLUPPERCASE)".
After extensive discussion there is the conclusion that ExactCase
is intended, so using a CamelCased name makes that more obvious.

Modify add_jar to fully use named arguments, rather than cmake
variables, for specifying output names/directories, etc. For backward
compatibility, the old variables are still honored if set, although
named arguments will override them.
Modify add_jar to (partly) use cmake_parse_arguments, and to require
using the named argument list INCLUDE_JARS to specify jar files (or jar
targets) to use as dependencies when creating a jar. This preserves the
ability to have such, while restoring the historic behavior that jar
files listed as sources are ignored. (The code now explicitly ignores
them, however, rather than adding them to an unused local variable, so
that it is more clear that nothing is being done with them.)
In GNU.cmake, -isystem is not used if APPLE is set. However, Clang has
pretty much always supported -isystem, so we should always use it.
In the future, GNU.cmake should do a version check to see if -isystem is
supported.
