cmake.lua error: couldn't find CMAKE_MAKE_PROGRAM
platform.lua error: toolchains was empty with wasm selected

wasm-test.zip

[waruqi]

why?

[Chi-EEE]

When I selected wasm as the platform, the toolchains list was empty but not nil, which did not allow me to install headeronly packages, but with this change, it allowed the code to find the toolchain for wasm

[waruqi]

it should not be empty.

[waruqi]

I can't reproduce this. You can print debug.traceback() when its empty.

or revert it and open an issue first. I will merge other patches.
