This can be used for example to organize all following targets into one
Visual Studio folder:
set(CMAKE_FOLDER Libraries)
add_subdirectory(libA)
add_subdirectory(libB)
set(CMAKE_FOLDER Executables)
add_subdirectory(progA)
Another possibility is using the current directory name for all
following targets in subdirectories:
get_filename_component(dirname "${CMAKE_CURRENT_SOURCE_DIR}" NAME)
string(APPEND CMAKE_FOLDER "/${dirname}")
Remove an unused variable and its containing local scope accidentally
left by commit v3.11.0-rc1~44^2 (Reduce allocation of temporary values
on heap, 2018-01-25).
Previously we dropped non-target items from the device link line because
nvcc rejects paths to shared library files, and only with target items
do we know the kind of library. However, this also prevents projects
from linking to system-provided libraries like `cublas_device` that
contain device code.
Fix this by passing more link items to device linking. Items that are
not file paths, such as `-lfoo`, can simply be passed unconditionally.
Items that are targets known to be shared libraries can still be
skipped. Items that are paths to library files can be passed directly
if they end in `.a`. Otherwise, pass them using `-Xnvlink` to bypass
nvcc's front-end. The nvlink tool knows to ignore shared library files.
Issue: #16317
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
When a `...<max>` version is given that is larger than the running
version of CMake, assume that the project is aware of a newer version of
CMake and that any unknown arguments are future arguments. This will
allow future versions of CMake to add arguments to the command that
projects can use without introducing errors in older versions of CMake
(back to 3.12).
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.
