CMake - Create executable for all *.cpp file in folder - c++

Question

I have this folder tree:
benchmark/
├─ pair/
│ ├─ benchmark_create.cpp
│ ├─ benchmark_insert.cpp
│ ├─ benchmark_remove.cpp
├─ set/
├─ CMakeLists.txt
And this is my current CMakeLists.txt file content:
add_executable(dbg_pair_creation pair/benchmark_creation)
target_link_libraries(pair_creation benchmark::benchmark)
add_executable(dbg_pair_insert pair/benchmark_insert)
target_link_libraries(pair_insert benchmark::benchmark)
add_executable(dbg_pair_remove pair/benchmark_remove)
target_link_libraries(pair_remove benchmark::benchmark)
There is a compacxt way to do the same and to put this executable in a folder with name pair that is the folder name of the source?

Answer 1

You could use a foreach loop.
set(benchmarks creation insert remove)
foreach (benchmark IN LISTS benchmarks)
add_executable(dbg_pair_${benchmark} pair/benchmark_${benchmark}.cpp)
target_link_libraries(dbg_pair_${benchmark} PRIVATE benchmark::benchmark)
set_property(
TARGET dbg_pair_${benchmark}
PROPERTY RUNTIME_OUTPUT_DIRECTORY
"${CMAKE_CURRENT_BINARY_DIR}/dbg_pair_${benchmark}"
)
endforeach ()
Then you would just need to add to the benchmarks list when you add a new benchmark.
