Ok, go try it. Create a simple python or perl script that reads a file.
The file just has a single number N inside it. And based on N the script
outputs those files:
Here's the CMake version:
cmake_minimum_required(VERSION 3.5.0)
project(cmaketest)
find_package(Qt5Core REQUIRED)
execute_process(
COMMAND python ${CMAKE_CURRENT_SOURCE_DIR}/generator.py --list
${CMAKE_CURRENT_BINARY_DIR}/genoutput 5
OUTPUT_VARIABLE fileList
)
string(REPLACE "\n" ";" fileList ${fileList})
add_custom_command(OUTPUT ${fileList}
COMMAND ${CMAKE_CURRENT_SOURCE_DIR}/generator.py
${CMAKE_CURRENT_BINARY_DIR}/genoutput 5
)
qt5_wrap_cpp(moc_files ${fileList})
add_executable(servertest servertest.cpp ${fileList} ${moc_files})
target_link_libraries(servertest Qt5::Core)
target_include_directories(servertest PRIVATE
${CMAKE_CURRENT_BINARY_DIR}/genoutput)
However, it is cheating in the same way that the QBS version from
Christian is cheating - it assumes '--list' exists:
In qbs:
outputArtifacts: {
var p = new Process();
try {
p.exec("path_to_script", ["--list", input.filePath]);
var files = p.readStdout.split("\n");
Christian, can you create a version which does not require --list? As
far as I understand, that is the point of the QBS dynamic build graph. I
would like to make sure my understanding is correct. I've attached the
generator and servertest.cpp if that helps.
Thanks,
