Previously, it was inconsistent in that some platforms/compilers
had this flag for the RelWithDebInfo configuration and some didn't.
This fixes issue #11366.
Since commit 571dc748 (Recognize Clang C and C++ compilers, 2010-05-17)
we recognize Clang C and C++ support. Add Compiler/Clang-ASM.cmake to
enable use of Clang for ASM too. Also teach Assembler test to try Clang
as an assembler.

Especially remove "lib64" when the given paths are all Unix ones and "lib" is
also explicitely given. In that case CMake will search "lib64" anyway for
platforms where it is known to make sense.
Instead of directly passing $ENV{SOMEVAR} to a find_* call pass in ENV SOMEVAR.
This will make sure the paths will get correctly handled through different
platforms, especially on Windows.
Also fixes one place where paths with windows delimiters (\) were hardcoded to
use forward slashes.
This was missed by commit 7bbaa428 (Remove trailing whitespace from most
CMake and C/C++ code, 2012-08-13) which only removed trailing spaces,
not TABs.
Ancient versions of CMake required else(), endif(), and similar block
termination commands to have arguments matching the command starting the
block. This is no longer the preferred style.
Run the following shell code:
for c in else endif endforeach endfunction endmacro endwhile; do
echo 's/\b'"$c"'\(\s*\)(.\+)/'"$c"'\1()/'
done >convert.sed &&

7e58e5b Prefer generic system compilers by default for C, C++, and Fortran
796e337 Factor common code out of CMakeDetermine(ASM|C|CXX|Fortran)Compiler
b708f1a CMakeDetermine(C|CXX)Compiler: Consider Clang compilers
Since commit c198730b (Detect Watcom compiler version with its id,
2011-12-07) the CMAKE_(C|CXX)_COMPILER_VERSION variables are set for the
Watcom compiler. Use these in Windows-wcl386.cmake to set the old
WATCOM1* version variables. This avoids using the old EXECUTE_PROCESS
command which failed due to extra quotes anyway.
This fix bug #0013451. The bug prevents theorerically relocatable RPM package
to be installed properly.

Teach CMake to prefer the system default compiler automatically when no
compiler is specified. By default use "cc" for C, "CC" for C++, and
"f95" for Fortran. Load a new Platform/<os>-<lang>.cmake module to
allow each platform to specify for each language its system compiler
name(s) and/or exclude certain names.
Create Platform/(CYGWIN|Darwin|Linux|Windows)-CXX.cmake modules to
specify "c++" as the system C++ compiler name for these platforms. On
systems that use case-insensitive filesystems exclude C++ compiler names
that are distinguished from C compiler names only by case.
This will change the default compiler selection for existing build
scripts that do not specify a compiler when run on machines with
separate system and GNU compilers both installed in the PATH. We do not
make this change in default behavior lightly. However:
(1) If a given build really needs specific compilers one should specify
them explicitly e.g. by setting CC, CXX, and FC in the environment.
(2) The motivating case is to prefer the system Clang on newer OS X
systems over the older GNU compilers typically also installed. On
such systems the names "cc" and "c++" link to Clang. This is the
first platform known to CMake on which "c++" is not a GNU compiler.
The old behavior selected "gcc" for C and "c++" C++ and therefore
chooses GNU for C and Clang for C++ by default. The new behavior
selects GNU or Clang consistently for both languages on older or
newer OS X systems, respectively.
(3) Other than the motivating OS X case the conditions under which the
behavior changes do not tend to exist in default OS installations.
They typically occur only on non-GNU systems with manually-installed
GNU compilers.
(4) The consequences of the new behavior are not dire. At worst the
project fails to compile with the system compiler when it previously
worked with the non-system GNU compiler. Such failure is easy to
work around (see #1).
In short this change creates a more sensible default behavior everywhere
and fixes poor default behavior on a widely-used platform at the cost of
a modest change in behavior in less-common conditions.
The compiler candidate list selection and search code for C, C++, ASM,
and Fortran languages was duplicated across four modules. To look for
compilers adjacent to already-enabled languages the C and CXX modules
each used _CMAKE_USER_(C|CXX)_COMPILER_PATH and the ASM module used
_CMAKE_TOOLCHAIN_LOCATION. Since commit 4debb7ac (Bias Fortran compiler
search with C/C++ compilers, 2009-09-09) CMake prefers Fortran compilers
matching the vendor and directory of an enabled C or C++ compiler.
Factor out the common functionality among the four languages into a new
CMakeDetermineCompiler module. Generalize the Fortran implementation so
that all languages may each use the vendor and directory of the other
languages that have already been enabled. For now do not list any
vendor-specific names for C, C++, or ASM so that only the directory
preference is used for these languages (existing behavior).
Look for "clang" or "clang++" compiler executables so Clang will be used
when it is the only compiler available. Prefer them last to avoid
changing compiler default preferences for existing scripts.
In case that any of the input variables that hold the library names contains
more than just a single library the "debug" or "optimized" keywords were only
prepended to the first item, making all other libs appear in all
configurations. Just treat both input variables as lists.
Thanks to Philipp Berger <newsletters@philippberger.de> for pointing me at
this.

bd34963 Refactor generation of shared library flags
55d7aa4 Add platform variable for flags specific to shared libraries
31d7a0f Add platform variables for position independent code flags
Store in new platform variables
CMAKE_${lang}_COMPILE_OPTIONS_PIC
CMAKE_${lang}_COMPILE_OPTIONS_PIE
flags for position independent code generation.
In almost all cases, this means duplication of the
CMAKE_SHARED_LIBRARY_${lang}_FLAGS for the _PIC case and using the
assumed pie equivalent for the _PIE case. Note that the GNU compiler
has supported -fPIE since 3.4 and that there is no -fPIC on GNU for
Windows or Cygwin.
There is a possibility that the _PIE variables are not correct.
However, as there is no backwards compatibility to be concerned about
(as the POSITION_INDEPENDENT_CODE property is not used anywhere yet),
the current state suffices.
cmcldeps wraps cl and adds /showInclude before calling cl.
It parses the output of cl for used headers, drops system
headers and writes them to a GCC like dependency file.
cmcldeps uses ATM ninja code for process handling,
but could be ported later to SystemTools.

If on APPLE, the phonon backend plugin is set to phonon_qt7. If on WIN32, the phonon backend plugin is set to phonon_ds9. I did not add any for generic UNIXes as they could have a whole host of things. A more comprehensive script would actually attempt to detect which phonon plugins were installed. However, this is a simple fix for now that will work for most people.
Using the QT4_ADD_RESOURCES() macro required the resource file to exist
already for dependency scanning. This prevented the use of resource
files that are generated by cmake because it needs the file before
resolving the dependency. This patch adds support for generated
resource files by not scanning the resource file for dependencies if it
doesn't exist yet. The add_custom_command() to generate the resource
file should add the dependencies on the files used by the resource file.

Fix the build command when Ninja is the CMake Generator, but the

Until now an unnamed component was always named "Unspecified".
Now this name is taken from the new cmake variable CMAKE_INSTALL_DEFAULT_COMPONENT_NAME,
which is initialized to "Unspecified". But it can now be set to something
project-specific, per directory
Alex
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.
By tracking a stamp file within the git clone script itself.
Avoids a 2nd git clone operation after switching from Debug
to Release builds in Visual Studio, or vice-versa.
Add "private/internal-use-only" function _ep_get_step_stampfile
to get the name of the stamp file for a given step.
The functionality provided by this commit should be identical
to its parent commit.
In the case of git, only track the repository in the
repository info dependency tracking file. Not the tag.
The download step should only re-run if the repository changes.
The download step should NOT re-run if the tag changes.
The update step is an 'always' re-running step, and so should
already re-run, unless it's been eliminated by use of
UPDATE_COMMAND ""
Use of the deprecated option with Intel 2011 produces
icl: command line remark #10010: option '/GX' is deprecated and will
be removed in a future release. See '/help deprecated'
so use its replacement option which has been supported for several
older versions anyway.
If CPACK_NSIS_ENABLE_UNINSTALL_BEFORE_INSTALL is set to ON the NSIS installer will look for a previous installed version and ask the user about uninstall.
Commit f67139ae added running a verify script in between running
the download and extract scripts. Since then, it has always been
missing the COMMAND keyword added in this commit.
It worked anyway (semi-accidentally) by running a command line like:
cmake -P script1.cmake cmake -P script2.cmake
CMake, when running -P scripts on the command line, runs them in order,
and apparently ignores spurious arguments in between (the middle "cmake"
in the above example) and so, all appeared to work as intended.
This commit adds the missing keyword and the commands that run are
now two separate sequential cmake invocations like:
cmake -P script1.cmake
cmake -P script2.cmake
...which was the original intent of commit f67139ae
Allows custom NSIS commands to run prior to any installation
actions. Projects that need to run an uninstaller first,
especially one from a non-NSIS previous revision of a project
that is NOW using CPack and NSIS, may do so by putting custom
NSIS commands into this variable.

Since commit 44d007b6 (CheckIncludeFiles: fix status output, 2012-02-01)
check_include_files reports the list of files tested instead of the name
of the variable storing the result. Some projects incrementally test
and concatenate very long lists leading to long messages that do not
provide much information. Users report confusion especially when the
lines wrap.
For lists of more than two files produce messages of the format
Looing for N include files first.h, ..., last.h
where N is the list length and "..." is literal. Leave the log file
entries and cache entry description unchanged as they should have the
full detail of the check performed.
The parent commit added a search path relative to OSX_DEVELOPER_ROOT.
But with Xcode 4.3 the nested Applications folder is in a different
relative location compared to that root. This commit makes the intent
of the previous commit work with older and newer Xcode directory layouts.
Furthermore, it only adds paths that exist to the search path.
Starting with Python3, standard Python installs may have additional ABI
flags attached to include directories and library names. As of 3.2, the
following flags are in the configure file:
d -> --with-debug
m -> --with-pymalloc
u -> --with-wide-unicode
Python 3.3 seems to no longer have --with-wide-unicode. Hopefully Python
will ensure that the possible flags always show up in a stable order.
The 'd' flag is ignored since the debug library is considered separate.
There is still the problem where ABI flags cannot be specified in
find_package since the letters confuse the version comparator.
If PYTHON_INCLUDE_PATH is put into the cache, then it will always
override whatever might be found and PYTHON_INCLUDE_DIR is never given a
chance to find something different. It being marked as INTERNAL also
means that it cannot be changed without editing CMakeCache.txt directly.
Basically, the scenario is that if the Python version is changed, then
deleting PYTHON_INCLUDE_DIR doesn't work because any cached
PYTHON_INCLUDE_PATH variable is set before find_path is even called. Any
build tree using a previous version will still need either manual
removal of PYTHON_INCLUDE_PATH or a complete reconfigure, but in the
future changing the Python version can be accomplished by deleting
PYTHON_INCLUDE_DIR and reconfiguring with the new version.

Also, the paths to the available SDKs changed: they are now within the

PackageMaker is installed as a separate program, and may be installed

Download the "Auxiliary Tools for Xcode" to get PackageMaker.
Put PackageMaker inside the Xcode.app bundle, in its nested Applications
folder, or put it alongside Xcode in "/Applications" and CMake will find
it.
Update references to "find" paths: add new possible locations for finding
Xcode.app and PackageMaker.app. Prefer the most recent version's locations
first, but keep the old locations as fallback search paths, too.

There are versions out there that neither understand --version nor -V. Try a
completely different approach: execute a small python script that prints the
version number (and only that) in an easily reusable way using
sys.version_info. This is documented to work since Python 2.0. Use sys.version
for older versions, which is documented to exist since 1.5. If even that
doesn't work then simply assume we are on 1.4.0.
This concerns all variables common to all CPack generators.
Variables mainly used and/or set in CPack.cmake are documented
therein. C++ built-in variables are documented in
cmCPackDocumentVariables.cxx.
Use CMAKE_<LANG>_COMPILER_VERSION instead of calling the compiler. This macro
predates those useful variables. This also fixes the issue that g++ version

The Borland compiler was re-branded as CodeGear during 2007-2009 and
since 2009 is the Embarcadero compiler. They offer predefined macros:
http://docwiki.embarcadero.com/RADStudio/en/Predefined_Macros
and distinguish themselves by __CODEGEARC__ and __CODEGEARC_VERSION__.
Version 6.30 (C++Builder XE) changed the meaning of some flags:
http://docwiki.embarcadero.com/RADStudio/en/C%2B%2B_Compiler_Option_Changes_for_XE
Teach Embarcadero compiler information files to generate build rules
with flags matching the compiler version. Leave the flags unchanged
for old Borland versions. Always set the BORLAND toolchain indicator
for compatibility with existing projects that test it. Also set the
EMBARCADERO indicator for newer toolchains.
The GenerateExportHeaders test was failing on one machine, the version
could not be determined there, so the _gcc_version was empty,
so the first argument to if() was empty, so it complained:
http://open.cdash.org/testDetails.php?test=135623436&build=2016288
Use double quotes to turn the non-existant first argument into an empty
string.
Alex
Since we know which compiler we have we can test those OpenMP flags first that
are likely to be correct. This doesn't make any difference for GNU compilers,
but it should avoid useless try_compiles and output cluttering for all others.
The Borland compiler is now the Embarcadero compiler. Rename the shared
platform information file to reflect this. This does not change the
interface, as old versions are still "Borland", but will allow new
versions released by Embarcadero to be supported cleanly.
Newer Ruby versions (from 1.9 onward) seem to warn if you query Config::CONFIG
and print a warning to use RbConfig instead. RbConfig seems to also work in
older versions, at least in 1.8. Use a macro to query RbConfig first and only
if that doesn't give anything fall back to Config.
This contains a change, which changes the behaviour a bit:
now X11_xf86vmode_FOUND is only set to TRUE and the include directory
is added to X11_INCLUDE_DIR, if additionally to X11_xf86vmode_INCLUDE_PATH
also X11_Xxf86vm_LIB has been found.
I hope this doesn't cause regressions somewhere.

Configure the build_mingw.cmake.in config_mingw.cmake.in files
into the binary directory of the directory being built, not the
top level binary directory for the project.
This also cleans up a bunch of things on the way:
-when perl was queried for paths they were not converted to CMake style on
Windows.
-the result when perl was queried for the perl library name was ignored since
it was expanded with the possible paths, which is not a valid input for
find_library(). If perl returns a library name we now will look only for this
name and not for the default names and use the default names only when the
executable does not give us a hint.
-get rid of 2 variables that were only used at one place and directly put the
values in the call to find_library() and find_path().
