Feature tests like CMake's check_include_file #404

Closed SirNate0 closed 1 month ago

Does build2 have any comparable feature's to CMake's check_include_file and related tests? E.g. those used by SDL all over this file? If not, how would one implement something similar (e.g. how would one build SDL with build2)?

The recommended way to deal with this is by adding the corresponding check to the libbuild2-autoconf module using the same approach as in the already existing checks. But there is a way to check for system headers in build2 by using $\.find_system_header() function, where the <module> can be either c or cxx (with potentially different results).

You can find more details in the following thread in the #build2 channel on Slack: https://cpplang.slack.com/archives/CDJ0Z991S/p1712758112177769

I am going to close this issue since it's more of a question (which, BTW, are better to ask in other places: https://build2.org/community.xhtml#help).
