This variable can be useful in cross-compiling contexts where the
sysroot is read-only or where the sysroot should otherwise remain
pristine.
If the new CMAKE_STAGING_PREFIX variable is set, it is used instead
of CMAKE_INSTALL_PREFIX when generating the installation rules in
cmake_install.cmake.
This way, the CMAKE_INSTALL_PREFIX variable
always refers to the installation prefix on the target device, regardless
of whether host==target.
If any -rpath paths passed to the linker contain the CMAKE_STAGING_PREFIX,
the matching path fragments are replaced with the CMAKE_INSTALL_PREFIX.
Matching paths in the -rpath-link are not transformed.
The cross-prefix usr-move workaround is assumed not to require extension
regarding CMAKE_STAGING_PREFIX. The staging area is a single prefix, so
there is no scope for cross-prefix symlinks. The CMAKE_INSTALL_PREFIX
is still used to determine the workaround path, and that variable
remains the relevant one even if CMAKE_STAGING_PREFIX is used. If the
generated export files are deployed to the target, the workaround
will still be in place, and still be employed if required.

f41ecd1 CMakeDetermineCompilerId: Look for internal file only on host
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.
Clang can compile code, but uses the gcc tools for other tasks such
as linking. The -gcc-toolchain option can be used for that, but
generalize so that other compilers can be treated the same.
If such a location is specified, use it as a hint for finding
the binutils executables.
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 ${arch})
Both clang and qcc are inherently cross compiler( driver)s.
When cross-compiling with clang, use the CMAKE_${lang}_COMPILER_TARGET
as the _CMAKE_TOOLCHAIN_PREFIX to find the appropriate binutils.
When cross-compiling with QNX qcc, use the CMAKE_${lang}_COMPILER_TARGET
to set the appropriate _CMAKE_TOOLCHAIN_PREFIX.
The find_file this module uses to locate the compiler id source file
must always look on the host and never in CMAKE_FIND_ROOT_PATH, even
when a toolchain file has
set(CMAKE_FIND_ROOT_PATH_MODE_INCLUDE ONLY)
Add NO_CMAKE_FIND_ROOT_PATH to the find_file call to avoid rerooting.

Manually revise the .rst format of the documentation. Use inline
literal quotes appropriately in paragraph text. Move the :: literal

command signature documentation and examples to cmake code-block

Drop the "Modules/CMakeVS*FindMake.cmake" files. Override the
cmGlobalGenerator::FindMakeProgram method for VS generators to use their
internal APIs to locate the build tool. Set the CMAKE_MAKE_PROGRAM as a
normal variable for use by project code, but do not cache it. This will
allow CMake and CTest to select the proper tool at build time.
Historically these were both added for the Makefile and Visual Studio
generators, respectively. Later the VS generators started using the
CMAKE_MAKE_PROGRAM cache entry to find the IDE build tool, and the
CMAKE_BUILD_TOOL was simply set as an alias.
Fix the documentation to explain that CMAKE_MAKE_PROGRAM is the modern
variable and that CMAKE_BUILD_TOOL is the compatibility alias, not the
other way around. Replace uses of CMAKE_BUILD_TOOL with
CMAKE_MAKE_PROGRAM in CMake-provided modules. Nothing needs to lookup
CMAKE_BUILD_TOOL in the cache, so simply set it as a normal variable.
The internal variables CPACK_ADDCOMP_COMPONENTS,
CPACK_ADDCOMP_STR and CPACK_ADDCOMP_UNAME were being needlessly

Prefixing them with an underscore prevents this.
CPACK_ADDCOMP_STR was particularily problematic since it contains
unescaped quotes.

Extend the RunCMake.ExternalData test to cover the non-failure message
case when stores are provided without URL templates.

As mentioned in commit 4693cf84 (Xcode: Detect new default locations of
Xcode 4.3 bits and pieces) PackageMaker was split out of Xcode 4.3 and
above into a separate Auxiliary tools package. Since Xcode 5.0 or so,
Apple no longer distributes PackageMaker as part of the available
development tools so it can only be obtained from old packages.
Disable the CPACK_BINARY_PACKAGEMAKER option by default as is the case
for most other tool-dependent generators.
In certain scenarios, it is preferable to keep a 'dirty' install prefix

3e04946 Require CMAKE_<LANG>_COMPILER to be found as a full path
6007f7c CMakeDetermineCompilerId: Always use compiler detected from IDE
332771c CMakeDetermine*Compiler: Remove temporary cache entry
All generators now support detection of the full path to the compiler, so
require it to be so. This will allow CMake<LANG>Information.cmake and
other logic to assume the full path to the compiler tool is available.
The Makefile generators already rejected CMAKE_<LANG>_COMPILER values
that did not name an existing compiler. Extend this error message to
all generators, make it occur as early as possible, and improve the
message with advice about how to set the compiler. If the full path to
the compiler is not known, finish enabling languages with a fatal error
so configuration does not continue.
For now, allow the RC language compiler to not be a full path. Later we
will need to detect the full path to "rc" under the VS IDE.
Add a RunCMake.CompilerNotFound test to cover failure cases.
Fix the RunCMake.CompilerChange test EmptyCompiler case to work
when configuration does not continue past enable_language.
When compiler id detection also provides a CMAKE_<LANG>_COMPILER
value, use it unconditionally. It is known to be the compiler
that is actually in use by IDE builds in VS and Xcode. Do not
let a stray cache entry try to say otherwise.
Teach the ctest_update implementation to use the p4 command-line
client to perform updates and extract the list of changes.
Add a CTest.UpdateP4 test like those that exist already for the other
version control tools. Make the test available when p4 and the p4d
server are found. During the test launch p4d in the background to
serve a repository from the test directory. Then direct the client
toward this server for the duration of the test.
One way to use clang as a cross-compiler is to create
a symlink named <target>-clang, which is equivalent to
running
clang -target <target>
Extract the toolchain prefix to find the binutils executables.
When the user or toolchain file sets CMAKE_<LANG>_COMPILER to a name
without a path we use find_program with CMAKE_<LANG>_COMPILER_WITH_PATH
to search for the tool. Remove the temporary cache entry afterward to
avoid exposing it to projects. It is not set by other logic paths so no
one should be using it.
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.

Drop all behavior activated by setting CMAKE_BACKWARDS_COMPATIBILITY to
a value lower than 2.4, and generate an error when projects or the user
attempt to do so. In the error suggest using a CMake 2.8.x release.
Teach cmake_minimum_required to warn about projects that do not require
at least CMake 2.4. They are not supported by CMake >= 3.0.
Replace the documentation of CMAKE_BACKWARDS_COMPATIBILITY with a
reference to policy CMP0001.
Even though this variable gets set to CMAKE_<LANG>_COMPILER-NOTFOUND when
the compiler is not found, CMake<LANG>Compiler.cmake gets removed by
cmGlobalGenerator::EnableLanguage so in try compiles the value is empty.
Quote references to the variable in
Modules/CMake(C|CXX|Fortran)Information.cmake
Modules/CMakeDetermineCompilerId.cmake
to avoid dropping arguments from commands that expect them.
Add "Module Documentation" and "Find Modules" subsections. Add to
Modules/readme.txt a textual reference to the cmake-developer.7 manual
and, while at it, fix the wiki URL domain.
Move all content from Modules/readme.txt except for the link to the
module maintainers wiki page into "Help/manual/cmake-developer.7.rst".
This produces some invalid reStructuredText markup to be fixed in a
future commit.
Previously if headers required to check the size of a type can be
compiled with C++ compiler only, the check would fail because the C
compiler fails. As a consequence, HAVE_${VARIABLE} would be set to
false, and ${VARIABLE} will be empty.
Teach CHECK_TYPE_SIZE to accept a new optional argument LANGUAGE
that allows one to explicitly set the compiler to use. The new
signature is therefore:
CHECK_TYPE_SIZE(TYPE VARIABLE [BUILTIN_TYPES_ONLY]
[LANGUAGE <language>])
Teach CMakeDetermineCompilerId to skip trying to build a .vfproj
file for Intel Fortran under Visual Studio 6. The msdev command-line
build produces a popup error dialog that hangs the configuration.
In generators such as Ninja that can run multiple "cl" processes that
refer to the same compiler .pdb file (/Fd) at the same time, MSVC from
Visual Studio 2013 complains:
fatal error C1041: cannot open program database '.../vc120.pdb';
if multiple CL.EXE write to the same .PDB file, please use /FS
According to "cl /?":
/FS force to use MSPDBSRV.EXE
Add the flag to compilation lines for this compiler version just after the
/Fd option.

a6fd17c VS: Fix CMAKE_<LANG>_COMPILER detection with Intel toolset (#14471)
The Intel Fortran 10 64-bit compiler incorrectly defines _MSC_VER to its
own version (1020) instead of the underlying MSVC tools version. Since
we expect the compiler to be used only with VS >= 7 tools, assume MSVC
version 13.0 if _MSC_VER is not greater than 1300.
Teach CMake(C|CXX|Fortran)CompilerId* to report the MSVC version
simulated by the Intel compiler, if any. Refactor the Windows-Intel
platform information helper module to load Windows-MSVC instead of
duplicating the information. Teach Windows-MSVC to understand when
it is loaded as the simulated Fortran compiler (its preprocessor is
simulated).
It designed to search for implementation of backtrace(3) routine.
Currently it is used in OpenBSD Ports for building Clementine
music player.
A lot of input from brad.king@ and neundorf@.
The Intel Fortran compiler needs the /fpp option to enable C
preprocessing. Without the option the compiler may warn and ignore
preprocessor lines instead of failing with an error. Detect the
warning and treat it as failure so that we move on to try /fpp and
detect the correct id. Without this it works only by luck because
Intel is the first compiler id in our detection source file.
Drop #end and #module. Convert #section to a subsection header.
Convert #variable to the cmake domain "variable" directive.
Convert #macro to the cmake domain "command" directive.
Perform minor formatting fixes in text near these changes.
Compilers for languages other than C and C++ on OS X may not understand

Previously if headers required to check if a struct has a member can be
compiled with C++ compiler only, the check would fail because the C
compiler fails. As a consequence, the result variable would be set to
false, even if the struct has that particular member.
