Allows exclusion of doc and related targets to help when using eigen via add_subdirectory().
Requested by:
https://gitlab.com/libeigen/eigen/-/issues/1842
Also required making EIGEN_TEST_BUILD_DOCUMENTATION a dependent option on EIGEN_BUILD_DOC. This ensures documentation targets are properly defined when EIGEN_TEST_BUILD_DOCUMENTATION is ON.
When the type is PATH an absolute path is expected and user-defined
values are converted into absolute paths relative to the current directory.
Fixes#1990

Note: Call the cmake_minimum_required() command at the beginning of the
top-level CMakeLists.txt file even before calling the project() command.
It is important to establish version and policy settings before invoking
other commands whose behavior they may affect. See also policy CMP0000.
- Introduce CMake option `EIGEN_SPLIT_TESTSUITE` that allows to divide the single test build target into several subtargets
- Add CI pipeline for merge request that can be run by GitLab's shared runners
- Add nightly CI pipeline
This prevents projects that add Eigen using `add_subdirectory` from using their own custom CMAKE_BUILD_TYPE and have Eigen respect the same custom flags.
* Unifying all loadLocalTile from lhs and rhs to an extract_block function.
* Adding get_tensor operation which was missing in TensorContractionMapper.
* Adding the -D method missing from cmake for Disable_Skinny Contraction operation.
* Wrapping all the indices in TensorScanSycl into Scan parameter struct.
* Fixing typo in Device SYCL
* Unifying load to private register for tall/skinny no shared
* Unifying load to vector tile for tensor-vector/vector-tensor operation
* Removing all the LHS/RHS class for extracting data from global
* Removing Outputfunction from TensorContractionSkinnyNoshared.
* Combining the local memory version of tall/skinny and normal tensor contraction into one kernel.
* Combining the no-local memory version of tall/skinny and normal tensor contraction into one kernel.
* Combining General Tensor-Vector and VectorTensor contraction into one kernel.
* Making double buffering optional for Tensor contraction when local memory is version is used.
* Modifying benchmark to accept custom Reduction Sizes
* Disabling AVX optimization for SYCL backend on the host to allow SSE optimization to the host
* Adding Test for SYCL
* Modifying SYCL CMake
Confirm that install directory is identical
before and after this simplifying patch.
```bash
hg clone <<Eigen>>
mkdir eigen-bld
cd eigen-bld
cmake ../Eigen -DCMAKE_INSTALL_PREFIX:PATH=/tmp/bef
make install

# Apply this patch
cmake ../Eigen -DCMAKE_INSTALL_PREFIX:PATH=/tmp/aft
make install

Features committed in 2016 have required cmake verison 2.8.11.
`sergiu Tue Nov 22 12:25:06 2016 +0100: target_compile_definitions`
Set the minimum cmake version to the minimum version that
is capable of compiling or installing the code base.
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.
find_package use
This commit allows the sources of the project to be included in a parent
project CMakeLists.txt and support use of "find_package(Eigen3 CONFIG REQUIRED)"
Here is an example allowing to test the changes. It is not particularly
useful in itself. This change will allow to support one of the scenario
allowing to create custom 3D Slicer application bundling associated plugins.
/tmp/eigen-git-mirror # Eigen sources
/tmp/test/CMakeLists.txt:
cmake_minimum_required(VERSION 3.12)
project(test)
add_subdirectory("/tmp/eigen-git-mirror" "eigen-git-mirror")
find_package(Eigen3 CONFIG REQUIRED)
and configuring it using:
mkdir /tmp/test-build && cd $_
cmake \
-DCMAKE_FIND_PACKAGE_NO_PACKAGE_REGISTRY:BOOL=1 \
-DEigen3_DIR:PATH=/tmp/test-build/eigen-git-mirror \
/tmp/test

There is currently a workaround for an issue in gcc that requires invoking gcc with the -fabi-version flag. This workaround is not needed for Clang and moreover is not supported.
