Is your feature request related to a problem? Please describe.

• Easy to support ios/android/wasm.
• Improve asan/debug build. [boost] boost 1.85.0 使用clang-cl工具链开启asan，在测试时显示找不到头文件"string.hpp" #4503

set_urls("https://github.com/boostorg/boost/releases/download/boost-$(version)/boost-$(version)-cmake.7z")
add_versions("1.86.0", "ee6e0793b5ec7d13e7181ec05d3b1aaa23615947295080e4b9930324488e078f")

Describe the solution you'd like

Create new package boost-cmake or use on_source + add_configs("cmake", {description = "Use cmake buildsystem", default = false, type = "boolean"})

why not default to cmake for newer builds?

[star-hengxing]

I'm not sure if using cmake directly would break downstream users.
Msys2 has switched to cmake, but someone reported a bug msys2/MINGW-packages#13608 (comment)

It's fine to build with cmake by default, but it's a good idea to leave a warning to remind the user that they can fallback to b2 and try building again.

we can attempt to add add_configs("cmake" and set it to true (default) + warning first.

if it will be broken, we can set it(false) to fallback to b2.
