Cpp-Taskflow

[clin99]

Cpp-Taskflow 2.2.0: https://github.com/cpp-taskflow/cpp-taskflow

From the repository:

A fast C++ header-only library to help you quickly write parallel programs with complex task dependencies.

I would like to contribute with this implementation https://github.com/Hopobcn/conan-cpp-taskflow

Current decisions:

• Used header-only template therefore Cpp-TaskflowConfigVersion.cmake, Cpp-TaskflowConfig.cmake and Cpp-TaskflowTargets.cmake are not packaged.
• cpp-taskflow requires C++17 so I decided to encode this requirement with compiler.cppstd subsetting:

  def configure(self):    
  if not self.settings.compiler.cppstd:
      self.settings.compiler.cppstd = 17
  elif self.settings.compiler.cppstd.value < "17":
      raise ConanInvalidConfiguration("cpp-taskflow requires c++17")

• cpp-taskflow requires posix threads in Linux/Mac & win32 threads in windows. I don't know what is the best current approach. Right now I manually add this information to cpp_info.cxxflags but its missing windows

  def package_info(self):
  if not self.settings.os == "Windows":
      self.cpp_info.cxxflags = ["-pthread"]

  Help would be welcomed

hi @Hopobcn as you already have a working recipe, would you like to try to submit it to the conan center index? thanks

[Hopobcn]

I'll have a look

[Hopobcn]

I've added a PR https://github.com/conan-io/conan-center-index/pull/431 to add v2.2.0 (finally! :-P)

[Hopobcn]

https://github.com/conan-io/conan-center-index/pull/431 has been merged. Maybe we could close this issue.
