In commit v3.4.0-rc1~18^2 (Disable shared library support when compiler
links statically, 2015-09-30) we tried to detect when the compiler is
not capable of linking shared libraries (possibly due to flags in use).
However, the approach is not robust against flags like `-nostdlib`.
Revert it for now pending another solution to the original problem.
Prior to commit v3.4.0-rc1~71^2 (Project: Determine default language
dialect for the compiler, 2015-09-15) we always guessed the default
language standard dialect based on the compiler version. This was not
reliable so that commit switched to computing the default language
standard dialect while detecting the compiler id.
When a toolchain file uses CMakeForceCompiler to set the compiler id
then the detection does not occur. Therefore commit v3.4.0-rc1~54^2
(Project: Don't require computed default dialect if compiler was forced,
2015-09-22) made the lack of detection an error only if the compiler was
not forced. However, this means that projects using CMakeForceCompiler
no longer even get the guess that we had before so <LANG>_COMPILER does
not work.
Due to the sophistication of CMake's compiler detection logic projects
should be ported away from using CMakeForceCompiler. In the meantime,
restore a guess of the default language standard dialect when the
compiler is forced.
In commit v3.4.0-rc1~71^2 (Project: Determine default language dialect
for the compiler, 2015-09-15) we added an "INFO:..." string to the
compiler id detection binary. The value can be optimized out of the
compiler id binary unless we force it to be included by making the
program behavior depend on it at runtime. Add references to the value
as we do for the other info strings already.

Our CMAKE_PLATFORM_IMPLICIT_LINK_DIRECTORIES setting is no longer needed
because CMAKE_<LANG>_IMPLICIT_LINK_DIRECTORIES is now populated with the
actual implicit link directories for the current toolchain. The old
values we hard-coded in CMAKE_PLATFORM_IMPLICIT_LINK_DIRECTORIES are not
relevant to modern toolchains, so simply drop them.

Also add GTK2_TARGETS variable containing all imported targets.
Previously, the GTK2_LIBRARIES variable was filled with the paths to the
libraries, and only the GTK2_XXX_LIBRARY variables contained the imported
targets.
Multiple languages for SLAs and the SLA UI can be added via the CPack
variables CPACK_DMG_SLA_DIR and CPACK_DMG_SLA_LANGUAGES. For each
language defined in the languages variable, CPack will search for
<language>.menu.txt and <language>.license.txt in CPACK_DMG_SLA_DIR.
If the sla directory variable is not defined, the old behaviour using
CPACK_RESOURCE_FILE_LICENSE is retained.
There is the global CMAKE_DL_LIBS setting which can be used instead. There are
even platforms where this is either empty because those functions are part of
the libc or is called entirely different, so this code wouldn't work reliable
anyway.
In some cases, CMake returned the following error:
-- Checking for module 'foo'
-- Package 'foo' not found
When the actual error returned by pkg-config was:
Package 'bar', required by 'foo', not found
Now, the actual error is forwarded to the user.
-- Checking for module 'foo'
-- Package 'bar', required by 'foo', not found
For the standard case (i.e. the package was indeed not found), the
CMake error was:
-- Checking for module 'foo'
-- Package 'foo' not found
But it now prints:
-- Checking for module 'foo'
-- No package 'foo' found
The associated test was also updated. ${last} refers to the last
CLI argument.
We support setting CMAKE_OSX_SYSROOT to a symbolic value like "macosx".
Modules/Platform/Darwin-Initialize.cmake takes care of finding the
actual SDK path on disk. Use that result to set CPACK_OSX_SYSROOT
instead.
Set variables in the platform information modules to tell the Ninja
generator what deps type to use instead of hard-coding conditions in the
generator itself.
This module was added by commit v2.6.0~1489 (...supporting embedded
compilers..., 2007-07-02) to avoid needing to build the compiler id
detection source on toolchains that need special flags or linker files
to produce executables. Since then CMake has learned other ways to
identify such compilers (e.g. passing vendor-specific version flags and
checking for vendor-specific banners in the output). Furthermore, CMake
now detects a lot more than just the compiler id during language
initialization in order to support things like <LANG>_STANDARD and
COMPILE_FEATURES. Therefore CMakeForceCompiler is no longer a viable
approach because it skips such detection.
One remaining challenge to support toolchains that require special
linker files is to build the test for a working compiler, compiler ABI
detection binary, and other try_compile cases. This will have to be
worked out as such cases are encountered.
Unset CMAKE_MODULE_PATH before calling find_package(Git) to ensure we do
not get a project-provided FindGit module that may not provide the
GIT_VERSION_STRING that we need. We do not need to restore the value
explicitly because this occurs inside the _ep_add_download_command
function call scope.
Refactoring in commit v3.4.0-rc1~77^2~1 (ExternalProject: Use
GIT_VERSION_STRING instead of custom method, 2015-09-17) forgot
to update the variable name used in an error message.
If the automatically selected SDK is newer than the host OS version
and no deployment version has been set then adjust the deployment
version to the host OS version. Otherwise the user won't be able to
launch the executables on the build host.
This is for example a problem on a MacOSX 10.10 host with Xcode 7
which only provides a MacOSX10.11 SDK.
Starting with sigc++ 2.5.1, c++11 must be enabled in order to use
sigc++. The GTK2::sigc++ imported target will automatically enable the
required build flags in order to build with the version found on the
system.

Teach CMakeDetermineSystem to check for a CMAKE_SYSTEM_VERSION setting
even when CMAKE_SYSTEM_NAME is not set. This will allow builds on the
host OS to target other versions of the OS without full cross-compiling.
When a user or a compiler wrapper adds '-static' to the compiler flags
then it will always link static binaries. Detect this from the compiler
id binary and disable TARGET_SUPPORTS_SHARED_LIBS. This will prevent
projects from accidentally adding shared libraries when the toolchain
does not support them. It also helps CMake avoid linking with flags
that require shared libraries to be supported.
On SunOS the -std=c++11 flag must be used for linking as well as
compiling. Until we implement support for this we cannot support
the CXX_STANDARD property except on Linux (where it was tested).
The latter is now the preferred URL for visiting cmake.org with a

Commit 7235334a (Project: Determine default language dialect for the
compiler., 2015-09-15) introduced a mechanism to determine the default
dialect used for the running compiler. If conditions in
the <CompilerId>-<Lang>.cmake file are such that compile features for
that version of the compiler should be supported, the _DEFAULT_STANDARD
is set to the computed value.
However, the CMakeForceCompiler module allows users to bypass execution of the
compiler by CMake. In that case, do not set the _DEFAULT_STANDARD variable at
all, which effectively disables the compile-features where the module is used.
No compile features have ever been recorded where the module is used so no
functionality is lost.
If variable is set to TRUE, values of all variables prefixed with CPACK_
will be escaped so special characters such as dolar sign, quotes or
foreward slash will not be lost. By default variable is treated as set
to FALSE for back compatibility.
The cpack_encode_variables macro is changed into a function to remove
scope pollution. There should be no other effects.
Move detection over to the compiler id logic where we have already
constructed the list of compiler flags from ARG1 and CMAKE_<LANG>_FLAGS.
Pass the flags when we execute "cl" with "/showIncludes". Also pass "/c"
because we only need to compile, not link. Check the compiler process
exit code before trusting its output.

If PYTHON_EXECUTABLE is set, then we should look for the libs in the

This commit ensures that FindPythonLibs has found the library before

Add a helper class private to "cmcmd.cxx" to contain the implementation.
Update the link logic to use the intermediate files directory for each
target to hold manifest and resource files before embedding into the
binary. Preserve the old behavior of placing the .manifest file next
to the binary when not linking incrementally even though it will be
embedded.
We use PATH_SUFFIXES to append "python<v>" to each candidate path. Do
not append it to the constructed list of python framework include
directories. Otherwise the combined path will never exist. Note that
the code doesn't yet try to match the suffixes "m" and "u" between the
executable, library, and include directory.
This cmake variable has been deprecated for over a decade, and using it
as an input could potentially cause unexpected results. We still need
to keep it as an output variable for compatibility though.
The calls to find_program now use NAMES_PER_DIR so that the first executable
(e.g. h5pcc) appearing on their PATH will get chosen. The HDF5_PREFER_PARALLEL
variable swaps the search order when it is set to true in the event that a
directory being search contains both h5cc and h5pcc.
When compiling with
LDFLAGS='-Wl,-z,relro -specs=/usr/lib/rpm/redhat/redhat-hardened-ld'
the compiler output includes a line like
COLLECT_GCC_OPTIONS='-specs=/usr/lib/rpm/redhat/redhat-hardened-ld' ...
that our link line regex matches due to an argument ending in "-ld".
Since it is not really the link line no implicit link information is
dectected. Exclude "VAR=..." lines from consideration as link lines to
fix this.
Since commit v3.1.0-rc1~635^2~7 (project: Add infrastructure for
recording CXX compiler features, 2013-10-17) we compile a test source to
a binary and then extract "<LANG>_FEATURES:..." strings from the binary
with the file(STRINGS) command. Add a newline at the beginning of the
string literal to be sure file(STRINGS) can extract the first entry as a
string independent of whatever else the compiler may put before the
storage it allocates for the literal within the binary.

Mangling is prevented by using a function instead of a macro for setting
default value of some CPack variables. Function is meant for internal use
in CPack.cmake only.
Old macro is deprecated but kept for backwards compatibility - was
intended for internal use only as it can't be used for CPack after
CPack.cmake script is included.
Patch removes local workarounds that were required by old macro,
fixes default setting of variables that by default inherit value from
another variable that already went through old default setting macro
(e.g. value of CPACK_PACKAGE_INSTALL_REGISTRY_KEY caused error for
wrong escapes if CPACK_PACKAGE_INSTALL_DIRECTORY contained escaped
back slashes) and provides a test for correct escaping of characters.

Generally for a module foo, SWIG generates (in Python mode)
an extension module _foo.so and a proxy Python module foo.py.
However, if -noproxy is specified, instead it builds only foo.so
(without the leading underscore). The custom command generated
by CMake correctly handles the removal of this underscore when
-noproxy is given; however, it still adds foo.py to the expected
outputs. This upsets build tools that expect foo.py to be generated
(for example, 'make' will run the SWIG command twice). Fix this
by removing foo.py from the set of extra generated files when
-noproxy is specified.
Add an OPENSSL_USE_STATIC_LIBS option to enable it. Adjust
CMAKE_FIND_LIBRARY_SUFFIXES to only look for .a and .lib files. Also

When the Fortran_HL component is specified, the hdf5_hl library is not included
in HDF5_LIBRARIES which causes a bunch of undefined references at link
time. This commit adds hdf5_hl to the list of libraries to search for when the
Fortran_HL component is specified.
Define HDF5_{Fortran_,}HL_COMPILE_LINE so that HDF5_{Fortran_,}HL_INCLUDE_DIR
and HDF5_{Fortran_,}HL_LIBRARIES are found when the macro is invoked for HL and
Fortran_HL components. (Use patch from debian cmake-data package.)
Starting with Xcode 7 the OSX and iOS SDKs contain only stub

Since commit v2.8.7~31^2 (HP: Drive shared library linking with compiler
front end, 2011-12-12) the C compiler is used to link shared libraries
instead of calling the linker directly, so linker options need to be
wrapped as -Wl,-foo instead of -foo.
