Per-source copyright/license notice headers that spell out copyright holder
names and years are hard to maintain and often out-of-date or plain wrong.
Precise contributor information is already maintained automatically by the
version control tool. Ultimately it is the receiver of a file who is
responsible for determining its licensing status, and per-source notices are
merely a convenience. Therefore it is simpler and more accurate for
each source to have a generic notice of the license name and references to
more detailed information on copyright holders and full license terms.
Our `Copyright.txt` file now contains a list of Contributors whose names
appeared source-level copyright notices. It also references version control
history for more precise information. Therefore we no longer need to spell
out the list of Contributors in each source file notice.
Replace CMake per-source copyright/license notice headers with a short
description of the license and links to `Copyright.txt` and online information
available from "https://cmake.org/licensing". The online URL also handles
cases of modules being copied out of our source into other projects, so we
can drop our notices about replacing links with full license text.
Run the `Utilities/Scripts/filter-notices.bash` script to perform the majority
of the replacements mechanically. Manually fix up shebang lines and trailing
newlines in a few files. Manually update the notices in a few files that the
script does not handle.
The matching expression added by commit v3.5.0-rc1~33^2
(GetPrerequisites: Define api-ms-win-* files as system libraries,
2016-01-19) did not account for absolute paths to the UCRT libraries.
We already recognize absolute paths to the MSVC runtime libraries.
Do this for UCRT libraries too.
Issue: #16240
Since commit v3.6.0-rc1~287^2 (GetPrerequisites: Fix
gp_resolved_file_type on non-canonical paths, 2016-03-08) we
accidentally convert relative paths (e.g. system dll file names) to
absolute paths even when we do not know the base directory. Fix this by
canonicalizing only paths that are already absolute.
Closes: #16240
When using `grep` to filter the output, add the `-a` flag to tell
it never to treat the output as binary. Otherwise when LANG != C
in the environment the non-ascii text may break the filter.
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`.
The `VS*COMNTOOLS` environment variables specify locations of VS tools
and are set during the VS installation. Use them in addition to the
hard-coded default install locations.
Canonicalize the input paths so we treat them both consistently,
in particular when comparing them via string operations. This
is needed for calls like
fixup_bundle("${CMAKE_INSTALL_PREFIX}/../test" ...)

As dumpbin.exe is no longer reliable for gcc libraries on MinGW because
it crashes on many common libraries like libgcc_s and libgfortran it is
now necessary too resort to using objdump for DLL dependency walking.
Using objdump has a secondary problem in that it generates a lot of
output for large libraries and causes fixup_bundle() to take many
minutes to process what took fractions of a second with
"dumpbin.exe /dependents".
Add a 'grep' pre-filter in the execute_process() command pipeline to
reduce this output to a minimum for a several orders of magnitude speed
up. If grep is not available just use the full output.
As there does not seem to be a reliable way of detecting MinGW, callers
of fixup_bundle() may have to set the variable gp_tool to "objdump" if
dumpbin.exe is installed on the build machine to stop it using the
broken MS dumpbin.exe for library dependency walking.
These all test the same variable for different values, so only one of them can
ever be true. This also allows to completely remove one variable that only
flagged if one of the conditions matched.
This is done by gathering LC_RPATH commands for main bundle executable and
using it for @rpath lookup in dependent frameworks.
All functions that need to carry rpaths to now take optional <rpaths> argument.
This enabled apps using @rpath to be bundled correctly, which will be necessary
for upcoming Qt 5.4 that will use @rpath for all frameworks.
Check that install_name_tool has -delete_rpath before using it.
Otherwise it will fail with Xcode 3.x on 10.5 which has no -delete_rpath
option for install_name_tool command, that was first introduced in 10.6
SDK, even that 10.5 supports LC_RPATH and @rpath.
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.
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 &&
git ls-files -z -- bootstrap '*.cmake' '*.cmake.in' '*CMakeLists.txt' |
egrep -z -v '^(Utilities/cm|Source/kwsys/)' |
egrep -z -v 'Tests/CMakeTests/While-Endwhile-' |
xargs -0 sed -i -f convert.sed &&
rm convert.sed
Change to consider a library embedded if it is found in a subdirectory relative to the
using executable/library. Previous commit considered them local.
This case is encountered when @rpath is used with framework libraries, which are inside a directory tree.
Handle @rpath much like other Unixes, by doing a find_file with the given directories.
Also, consider a library to be local if it is found in the same directory or a subdirectory relative to the user
executable/library. Previously, it was local only if found in the same directory.
This case is encountered when @rpath is used with framework libraries, which are inside a directory tree.
Also add a test of BundleUtilities including an exe,
some shared libs, a plugin, and a framework-style lib.
This test presently runs (and this functionality works)
on Linux, Mac and Windows.
For now, the framework-style lib is built as a plain old
shared lib because there is another yet-unresolved issue
with local frameworks without rpaths on the Mac.
Fix IF(WIN32) guards check for cygwin. Fix checking if the depenency is in a system location to use cygwin style paths on cygwin. Also change GetPrerequisites to switch gp_tool to tools that are very unlikely to be found, ie. dumpbin on Apple and otool on Windows/Unix.
Users PATH may contain elements that end with backslash. This will escape the semicolon when iterating resulting in mismatches.
Fix indentation.
Fix whitespace
IF(... MATCHES ...) used for comparing directories chokes especially in the case of C:\Program Files (x86)\<blah> because of regex pattern matching. Switched this to use STREQUAL in a loop instead.

Conflicts:
Modules/BundleUtilities.cmake
There was one newly added function in BundleUtilities.cmake
which also needed the same "documentation at top" treatment.
ldd can return "not found" and we need to handle it correctly.
In that case, we extract only the name of the library instead of trying for its full path.
Put the function documentation into the header-comment, improve
formatting and list the user-relevant functions first.
