Add a new SOURCE_SUBDIR option to ExternalProject_Add that allows
specifying the location of the CMakeLists.txt to use as the project root
relative to the SOURCE_DIR.
This is helpful for projects that have unusual layouts, or projects that
provide both a superbuild and project-only build depending on which
CMakeLists.txt is used.

1aa5c1be FindCUDA: Fix missing librt on Linux when using static cuda runtime.
aab1f6e9 FindCUDA: Restore default behavior of CUDA_USE_STATIC_CUDA_RUNTIME
Android NDK builds are always `debug` or `release`. We may populate
flags for these configurations that are needed to produce compatible
binaries. Ensure they are used by default.
The Android NDK source repository at
https://android.googlesource.com/platform/ndk.git
has `<ndk>/build/core/toolchains/*/setup.mk` files that store tables of
information for their build system. Add an equivalent file for each
compiler/abi combination.
Commonly used Android toolchain files that pre-date CMake upstream
support may need to be updated to work with our new functionality.
They typically set CMAKE_SYSTEM_VERSION to 1, so detect that and
skip our upstream Android settings. When such toolchain files are
updated to account for our upstream support, they can then set
CMAKE_SYSTEM_VERSION to a valid Android API and get new behavior.
Commonly used Android toolchain files that pre-date CMake upstream
support use a few environment and CMake variables as search locations.
Use them too to aid transition.
Compute CMAKE_SYSROOT automatically for the current API and architecture
selection. This causes the --sysroot option to be passed to GNU and
Clang compilers.
Store the Android API level in CMAKE_SYSTEM_VERSION. If it is not
provided by the user, initialize it from CMAKE_ANDROID_API or fall back
to finding the latest available in the NDK.
Support for NVIDIA Nsight Tegra Visual Studio Edition was previously
implemented in the CMake VS IDE generators. Avoid interfering with
that functionality for now. Later we may try to integrate this.
Provide a way for Platform/<os>-Determine-<lang>.cmake modules to save
platform-specific information about the compiler in the configured
CMake<lang>Compiler.cmake modules.
Once CMAKE_SYSTEM_NAME is known, load a platform-specific
Platform/<os>-Determine
module in order to enable custom determination of the other settings
needed for the CMakeSystem module (e.g. CMAKE_SYSTEM_PROCESSOR). Also
add a hook in Modules/CMakeSystem.cmake.in to allow platform-specific
information to be saved.
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.

Commit 7229ae72 (FindCUDA: Refactor Android(Tegra) support, 2016-04-19)
changed the logic to only add librt to the link line for CUDA versions
6.5 and older. However, newer versions of CUDA still require librt.
Fix bug introduced by commit 7229ae72 (FindCUDA: Refactor Android(Tegra)
support, 2016-04-19). `CUDA_USE_STATIC_CUDA_RUNTIME` should be enabled
by default if `cudart_static` is available, and silently disabled if
it is not.
CMake used to put all header search paths into HEADER_SEARCH_PATHS
attribute. Unfortunately this attribute does not support to declare
a search path as a system include.
As a hack one could add a -isystem /path to the cflags but then include
ordering is not deterministic. A better approach was chosen with this
patch by not filling HEADER_SEARCH_PATHS at all and to populate
the C, C++, and Fortran flags directly. The include paths used by
Xcode should be now identical to the ones used by Unix Makefiles and
Ninja generator.
The Numerical Algorithms Group (NAG) Fortran compiler documents -PIC for
position-independent code and does not have a separate option for PIE.
We added `-PIC` for PIC in commit v2.8.11~174^2 (NAG: Use -PIC for
Fortran position-independent code, 2013-02-18). Follow up for PIE.
Closes: #16236
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.
Find modules only detect 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.
This approach is recommended by documentation in `cmake-developer(7)`
added by commit v3.2.0-rc1~286^2~1 (Help: Document IMPORTED_CONFIGURATIONS
target property for Find modules, 2014-12-04).
