[question] How does Conan compile indicators package successfully?

[hwhsu1231]

Problem Description

Recently, I compile the indicators sample codes followed by this. It turns out to be a failure, and I don't know why. So I post an issue on it:

• [bug] Cannot compile the sample codes with MSVC compiler on Windows. p-ranav/indicators#111

However, Conan can compile the indicators successfully. Why can Conan do it? What do I miss to compile the indicators myself?

• indicators is header-only, so recipe copies headers and doesn't rely on upstream CMakeLists
• test package is simple, it is not equivalent to all samples you build
• test package was run with gcc on Linux only last time indicators recipe was updated (previous logic for header-only libs). Maybe it would fail now since Visual Studio is always tested.
