Dynamic dispatch using cmake dont work

[junqueira200]

Hi,

I'm traing to compile an example of dynamic dispatch using cmake. I've got this error: payload.cpp:24:28: fatal error: payload.cpp: No such file or directory
24 | #define HWY_TARGET_INCLUDE "payload.cpp"

The complete example can be found here
Tried using macos in arm and x64 using linux.

The Highway was add by: git submodule add https://github.com/google/highway.git external/highway

To compile:
cmake .. -DCMAKE_CXX_FLAGS="-DHWY_COMPILE_ALL_ATTAINABLE"
make -j4
There is a build.sh

Thanks in advance for any help!

@junqueira200 Need to add the current source directory to the compiler include path by adding the target_include_directories(teste PRIVATE ${PROJECT_SOURCE_DIR}) line to CMakeLists.txt below the add_executable(teste payload.cpp driver.cpp) line.

@johnplatts Thanks!
Now I get:
Undefined symbols for architecture arm64: "hwy::VQSort(double*, unsigned long, hwy::SortAscending)", referenced from: hwy::CostDistribution::RemoveOutliers() in profiler_example.cc.o hwy::CostDistribution::RemoveOutliers() in profiler_example.cc.o

Similar error in x64.

Similar error in x64.

@junqueira200 Need to at least disable examples, install, and tests for Highway by adding the following lines to CMakeLists.txt:

set(HWY_ENABLE_EXAMPLES OFF)
set(HWY_ENABLE_INSTALL OFF)
set(HWY_ENABLE_TESTS OFF)

An example of a CMake-based project that uses Google Highway can be found at https://github.com/johnplatts/simdhwyhash (which is an implementation of HighwayHash that uses Google Highway).

This project don't compile with recent cmake. Do you have a small example of Dynamic dispatch using cmake?
