@hartmannathan try this with cmake
```
cmake_minimum_required(VERSION 3.16)
project(ManySources C)
set(srcs "")
# Increase MAX_SRC_FILE_INDEX value as needed
set(MAX_SRC_FILE_INDEX 5000)
set(TEST_SRC_FILE_BASE_NAME
"this_is_a_test_src_file_with_a_quite_lengthy_name_to_simulate_very_long_command_line_length_problems_on_host_")
foreach(i RANGE 1 ${MAX_SRC_FILE_INDEX})
set(src "${CMAKE_CURRENT_BINARY_DIR}/src/${TEST_SRC_FILE_BASE_NAME}${i}.c")
file(WRITE "${src}" "int s${i}(void) { return 0; }\n")
list(APPEND srcs ${src})
endforeach()
add_library(foo ${srcs})
```
