Since commit v3.11.0-rc1~467^2 (VS,Xcode: Add CMakeLists.txt sources
without mutating targets, 2017-10-18) we do not add `CMakeLists.txt` to
target sources but instead generate references to them directly. This
broke projects that explicitly specify their `CMakeLists.txt` file as a
source file because the explicit entry is no longer consolidated with
the generated one.
Teach the relevant generators to avoid duplicating `CMakeLists.txt`
source references and add test cases.
Fixes: #17828
In commit v3.11.0-rc1~68^2 (CPack: accept --trace and --trace-expand,
2017-12-09) a nullptr dereference was added that occurs when
`cpack -G NotAGenerator` is invoked. Add the needed condition.
Fixes: #17900
Some code paths in `ExpandVariablesInString{New,Old}` were not checking
the `filename` parameter for a null pointer, but this can happen when
using the above flags together. Add the checks and a test case.
Fixes: #17896
The output of moc/uic/rcc used to be discarded unless
the program failed. This lets moc/uic/rcc print their
output to stdout even on success.
Closes#17860
This adds a dedicated mutex for file reading and writing to
cmQtAutoGenerator::FileSystem. The purpose of the change is
to avoid that long files reads block cmsys based path computations,
which are protected by an other mutex.
Refactoring in commit v3.9.0-rc1~156^2 (c++: prefer vectors over lists,
2017-05-04) switched `cmCTestSVN::Repositories` from `std::list` to
`std::vector`. This can cause re-allocation when svn externals are
processed and break the `RootInfo` pointer that is supposed to point at
the first repository element. Switch back to `std::list` so that the
address remains stable.
Fixes: #17854
Revert commit v3.8.0-rc1~305^2 (Remove CTestTestfile.cmake when BUILD_TESTING
is OFF, 2016-11-14) again. We reverted it once in commit v3.8.0-rc3~22^2
(Revert "Remove CTestTestfile.cmake when BUILD_TESTING is OFF", 2017-03-06) but
it was accidentally restored by commit v3.11.0-rc1~387^2 (server: add
"ctestInfo" request to get test info, 2017-10-25), perhaps due to conflict
resolution during rebase.
We cannot remove `CTestTestfile.cmake` when testing is off because it breaks
projects that never enable testing but create their own `CTestTestfile.cmake`
manually instead. Revert the change again and add a test case.
When evaluating include directories during export to a `try_compile`
test project, thread the compile language through to the generator
expression evaluator so it can support `$<COMPILE_LANGUAGE:...>`.
Issue: #17811
When evaluating `INTERFACE_SYSTEM_INCLUDE_DIRECTORIES`, or evaluating
`INTERFACE_INCLUDE_DIRECTORIES` on an imported target, thread the
compile language through to the generator expression evaluator so
that it can support `$<COMPILE_LANGUAGE:...>`.
Fixes: #17811
Calling `std::string::front()` on an empty string results
in an undefined behavior by the C++ standard.
In gcc8 it causes an assertion to fail.
This adds a check to `AUTOGEN` if a file to read is empty
and in case avoids the use of an empty `std::string` buffer.
Closes#17793
In case CMAKE_XCODE_GENERATE_TOP_LEVEL_PROJECT_ONLY has been enabled
generate only the root-level ZERO_CHECK target so targets in
subdirectories pick up the root generator target of ZERO_CHECK.
For the case that CMAKE_XCODE_GENERATE_TOP_LEVEL_PROJECT_ONLY is not
enabled more investigation and a proper and final fix is still needed.
Issue: 14297
Some environments require linking to thread libraries for `std::thread`.
Express this direct dependency of CMakeLib explicitly. Previously this
was done indirectly through our bundled libuv, but that does not work
when using a system libuv.
Fixes: #17757
The `LINK_ONLY` generator expression is used to represent private
dependencies of static libraries in their `INTERFACE_LINK_LIBRARIES`
property value. Fix evaluation of generator expressions during export
to support the `LINK_ONLY` genex. Extend the RunCMake.AndroidMK test
with a case for this.
When exporting `INTERFACE_LINK_LIBRARIES`, we must evaluate generator
expressions first, before expanding the `;` list, in case they contain
or generate semicolons.
Check if the content of the AUTOMOC/UIC/RCC info file
will change before overwriting it. This avoids unnecessary
AUTORCC rebuilds when AUTORCC unrelated CMake settings change.
