emcmake find_library MATH

[Sergio González]

Hello,

I am using emcmake to build a c++ project as a wasm library. I am facing an issue where in the CMakeLists file I try to get the libm package using `find_library(MATH m)` but I get an error saying that the `MATH` variable is set to NOTFOUND.

Is there a flag that I need to provide somewhere in order to find MATH with emcmake?

Cheers!

Sergio

Emscripten uses musl libc, which doesn't have a separate math library (its just part of `-lc`).    I'm not sure setting `MATH` to `NOTFOUND` is the desired behaviour in this case but it seems reasonable.    What happens if you try building your project on a musl-based linux distro such as alpine linux?

cheers,

sam
