Error on emcmake emmake

I use emcmake and emmake in my Mac.
command :
mkdir build
cd build
emcmake cmake .. --preset ~~
emmake make

emcmake is done without any error, but emmake didn't work
this error is occurred.

make: *** [all] Error 2
emmake: error: 'make' failed (returned 2)

In other environment it is done well but it didn't work only in Mac.
And, cmake, make without emcmake, emmake are done well.
What is the problem?
