We no longer define the ZLIB_LIBRARY cache entry, so we should not mark

Extend the optimization from commit v3.4.0-rc1~264^2 (GetPrerequisites:
Optionally filter "objdump" output for speed, 2015-07-29) to work
on Windows by using `findstr` in place of `grep`.
FindBoost only detects Debug and Release configurations. All other
configurations will fall back to the configuration listed as the first
entry in `IMPORTED_CONFIGURATIONS`. Switch the order so that `Release`
is listed first, as this is a better fallback than `Debug` for the
`RelWithDebInfo` and `MinSizeRel` configurations. See issue #16091.
In commit v3.6.0-rc1~279^2~10 (VS: in Clang/C2 toolset, setup correct
compiler settings, 2016-02-18) a flag mapping was added for the clang
`-Os` flag. However, this collides with a mapping we already had for
the MSVC flag of the same name. This is a symptom of a larger problem
in that the VS generators need a per-toolset flag map (issue #16153).
For now, simply drop the new mapping and drop `-Os` from clang compiler
flags in the MinSizeRel configuration.

When enabling the CUDA static runtime, the current module always uses

Modify logic to unconditionally create an empty class list response file
to instead only create the empty file if no classes are being compiled.
Otherwise, the response file is created via a custom command that
generates the correct list.
This fixes a race condition on certain systems (e.g. HFS on OS X) where
the dependency for creating the "correct" list can have the "same" (due
to limited precision of the filesystem) timestamp as the empty file
created at configure time, resulting in an empty class list being
incorrectly used to invoke `jar` (resulting in `jar` being unhappy that
it was not given any input files). Although one would have some hope
that this doesn't affect "real" projects, it definitely does affect the
JavaExportImport unit test, causing the same to fail randomly when run
on an HFS partition.
Add additional functions to UseJava.cmake to create "exported" targets,
similar to those of C/C++ libraries. In support of this, ensure that the
JAR_FILE property of jar targets is always an absolute path.

Follow the configure_file by a file(GENERATE) so the resulting cmake
scripts used by FindCUDA for wrapping nvcc calls can now support
generator expressions in the CUDA_NVCC_FLAGS variable.
Prevent accidental inter component dependency setting
since this is a breaking feature in situations where
another CPack module is already using the feature.
It should be enabled if desired since it can cause
issues when upgrading only one of the components
for e.g. configuration instead of all the components
at once.
This patch preserves backward compatibility of
deb package names with previous CMake versions
but similarly to CPack/RPM allows to change
package name format and supports DEB-DEFAULT
setting that produces proper Debian package names.
GIT_VERSION_STRING is unset in _ep_write_gitupdate_script(), hence
git stash is not being called with the "--all" option, even if Git
is new enough to support this.
Move the content to a `ExternalProject-download.cmake.in` file and use
`configure_file` to generate the final script.
Retry logic was not working before because similar script trigger
FATAL_ERROR if 'file(DOWNLOAD ...)' exits with nonzero 'status_code'.
FATAL_ERROR makes the whole chain of commands stop and
'_ep_write_verifyfile_script' retry logic was not used in fact.
Default retry number set to 5 with pauses 0, 5, 5, 15, 60 seconds. Some
space left for future improvements if needed (90, 300, 1200=20min). Can
be controlled by user.
The purpose of the `update` step is to run an update on each build
(subject to `UPDATE_DISCONNECTED`). This is done for version-controlled
source directories. We should do it for a custom `UPDATE_COMMAND` too.
In particular, when `UPDATE_DISCONNECTED` is used we expect the
`skip-update` step to exist.
The `CMAKE_PLATFORM_REQUIRED_RUNTIME_PATH` is used by CMake to always
append `-Wl,-blibpath:/usr/lib:/lib` to the link line. This is needed
by default on these platforms but needs to be overridden in some use
cases (e.g. an environment in which one maintains versioned shared
libraries). Change our logic to set this value only if it not already
set by the user, project, or toolchain file.
Run the `Utilities/Scripts/clang-format.bash` script to update

This supplements the existing library checks, to
cater for the possibility that the libraries are
present but the headers are not. This can happen
when the Boost collections is split up into
multiple packages and not all are installed,
and will avoid the checks silently passing when
the build would subsequently fail.
Packagers may now set their own rpm package
file names or request that rpmbuild tool
chooses one for them. It also supports handing
of situations where one spec file may produce
multiple rpm packages.
The fix in commit v3.1.0-rc1~544^2~5 (Windows: Avoid () in environment

23a71e4e ExternalProject: Tell Git not to verify certs only if TLS_VERIFY is OFF
Teach CTestCoverageCollectGCOV to honor the
CTEST_EXTRA_COVERAGE_GLOB variable. When this variable is set,
this module will glob for matching source files that were not
covered and include them in the resulting tar file.
Since commit 272779ce (ExternalProject: Allow TLS_VERIFY for git clones,
2016-04-01) we pass the `-c http.sslVerify=false` option to `git clone`
even if no explicit `TLS_VERIFY` option was set. This changes behavior
because we used to use the default Git behavior by default. Revise the
logic to preserve the old default behavior by passing the new option
only if `TLS_VERIFY` was explicitly passed as `OFF`.
While at it, also honor `CMAKE_TLS_VERIFY` if the explicit `TLS_VERIFY`

Depending upon the configuration, certain components may or may not
be installed, for example Boost.Regex, but other components may
still have header dependencies upon these components which will
obviously fail to work. Since we can't make a sensible
determination with the hardcoded dependency information, we
choose to interpret these dependencies less strictly.

If CMAKE_INSTALL_RPATH is set and contains $ORIGIN then
dpkg-shlibdeps searches for the DEBIAN directory in order

Since commit v3.5.0-rc1~47^2 (FindCUDA: Support special characters in

CMake will automatically quote special characters correctly. However,
this breaks the special `$(VCInstallDir)` placeholder used with Visual
Studio generators. Since we do not support preservation of such
placeholders with VERBATIM (see issue #15001) we must fall back to not
using VERBATIM when the placeholder is used.
A better fix would be to stop using `$(VCInstallDir)` and use the value
of `CMAKE_${CUDA_C_OR_CXX}_COMPILER` instead, but that will require
additional semantic and documentation changes. For now simply fix the
regression with the above approach.

We deprecated this module in commit v3.5.0-rc1~295^2
(CMakeForceCompiler: Deprecate this module and its macros, 2015-10-19)

it. Indeed we still need to provide a way to work with toolchains that

warnings until we can provide an alternative to the module for this use
case.

CPACK_* variables expect component name in upper case.
CPACK_RPM_* variables expected component name to be
in same case as component name.
This patch adds support for CPACK_RPM_* variables with
upper case component names to match the convention with
CPACK_* variables and also preserves same case component
names for back compatibility.
The specific cause is when e.g.
/Library/Frameworks/GStreamer.framework/Versions/1.0/lib/libgio-2.0.0.dylib
is detected by fixup_bundle. set_bundle_key_values() interprets this as
a framework, thus doing a string replace that creates an embedded_item
that is equal to the original path, i.e. it is not embedded.
Before this change, the variable PROTOBUF_LIBRARIES might get redundant
value for debug and optimized configurations, e.g.
`optimized;/usr/lib/libprotobuf.so;debug;/usr/lib/libprotobuf.so`.
Some projects may want to use the detailed mangling information
directly instead of using the FortranCInterface_HEADER function.
We already provide variables encoding the mangling information,
so just document them as available.
This commit introduces two new options to CTestCoverageCollectGCOV.
When GLOB is set we recursively search in the source & binary
directories for .gcda files. Otherwise the default behavior is to
parse TargetDirectories.txt for a list of locations to search.
When DELETE is set we remove any .gcda file found after it has
been used to generate the corresponding .gcov file. The .gcov
file is also removed after the result tarball has been created.
Together these two new features help support the use case of
computing coverage across subprojects.
81ecc726 FindCUDA: Added some additional comments about non-existent dependency files.
4b561b4c FindCUDA: Fix for when a non-existent dependency file is found.
Due to #4662 -isystem support was disabled for all GNU Compilers
on Apple platforms. But the change was probably a just work around
for a broken compiler on Tiger (see 10837#c27206). So we tighten
the condition to only kick in for GCC versions earlier than 4.
That should ensure sane behavior for Xcode 3.2 and later.
Previously if a non-existent dependency file is found we set the file to "" and
then do if(NOT IS_DIRECTORY "${file}"). Later we call get_filename_component
on the empty file which returns basically the current build directory.
Having a dependency on the current build directory is really annoying, because
anything that compiles into that directory will change the file stamp and
cause your files to rebuild every time you call make. :(
Since commit v3.5.0-rc1~32^2~1 (ExternalProject: Simplify `cmake
--build` configuration passing, 2016-01-19) we use the `$<CONFIG>`
generator expression to generate the `cmake --build . --config <config>`
value for the default BUILD_COMMAND instead of the CMAKE_CFG_INTDIR
placeholder value provided by multi-config generators. However, some
projects have been abusing the old implementation detail by setting
CMAKE_CFG_INTDIR themselves to get a specific configuration. Those
projects should be updated to set their own BUILD_COMMAND to get
non-default behavior. Meanwhile we can be compatible with their
existing releases by detecting when CMAKE_CFG_INTDIR is not a
generator-provided placeholder and using its value instead.
The dependency flags require recent versions of `iccarm` and `iccavr`.
The multi-rule dependency generated with `--dependencies=m` does not
work well with Ninja, so use `--dependencies=ns` instead.
Imported targets are now the recommended way of dealing with external
library dependencies. Add one for FindPNG and update documentation
accordingly. Also add a test case activated by CMake_TEST_FindPNG.
Check CMAKE_CONFIGURATION_TYPES instead of CMAKE_CFG_INTDIR in order
to recognize multi-config generators. Then use $<CONFIG> to pass
the configuration value.
