[Feature] Install dependencies using CMake

[Shreyas Atre]

Expected Behavior

• Follow https://github.com/SAtacker/hpx-template cmake fetch content to download hwloc and boost dependencies depending upon the platform.

• Allow user to have configurable behaviors i.e. system can find boost which is already existing. Enable users to fetch content boost and hwloc usingHPX_WITH_FETCH_BOOST=ON and HPX_WITH_FETCH_HWLOC=ON

• Add tests for the same

Hello @SAtacker , is this issue open for anyone to work on, or only Shanmukh-C is supposed to work on it?
I have decent experience with CMakeLists.txt
And for testing out options, I created a clone of your repository: https://github.com/vrnimje/hpx-temp/tree/cmake
and tested out some workflows as well: https://github.com/vrnimje/hpx-temp/actions

Yes, you can definitely work on this! Seems like you have already looked into it.
(We have plenty of things to work on so you folks don’t have to worry)
What’s your id for discord on the IRC for STE||AR Group?

Thanks for the confirmation. Will get started with working on the issue right away. Just had a couple of queries:

1. Changes should be made in the main CMakeLists.txt of this repository, right?
2. Do tests (mentioned in 3rd pt. of the issue), mean workflow build tests?

And here is my Discord ID: verve0304

You'll have to figure that out yourself. But yeah, some of the mechanism can also be found in https://github.com/STEllAR-GROUP/hpx/blob/master/cmake/HPX_SetupBoost.cmake , use your best judgement and make reasonable code changes.

Do tests (mentioned in 3rd pt. of the issue), mean workflow build tests?

Yes, there are a few workflows in https://github.com/STEllAR-GROUP/hpx/tree/master/.github/workflows you can add your newly added cmake variable options as a separate test case(s) and try to compile and verify.

Update:
I have added the HPX_WITH_FETCH_HWLOC option here, and is working perfectly for Linux and MacOS. Test for Linux & MacOS

In Windows, it builds correctly but the tests fail: Workflow run

Could please you make a PR ?

Hello @SAtacker , I have tried adding the HPX_WITH_FETCH_BOOST option, and it is compiling for Linux and Windows, but in macOS the find_package call is not able to find Boost.Context here

Here are the modifications I have made: HPX_SetupBoost.cmake

Can you please take a look? Should I open a PR?

I have not included find_package(Boost) in my cmakelists

Thanks, turns out there was an unnecessary add_library call, before building Boost.

Update:
I have added the Boost Fetch option as well, and it is building successfully for Linux and Windows
In macOS, the unit tests fail to build, due to following error, but the main project builds successfully.

Another random popin! Maybe try it on another macOS machine

[Vedant Nimje]

Fixed the error
Caused due to cmake build type by default being set to Release
Just had to add -DCMAKE_BUILD_TYPE=Debug in the workflow

Builds on macOS successfully: build

@SAtacker The HPX_WITH_FETCH_BOOST option is also implemented, so should we proceed with the PR?
