Proper build and test steps

Hi, I am trying to enable tests for alpine linux and split in to separate build and test steps. If I run cmake with "-DWITH_TESTS=ON” It compiles the tests with "make all”, but it runs them as well. I have looked through the generated makefile and can’t see a target to just build ceph, the gentoo buildscript uses "make all" for build and "make check” for test. Is there any target that is just building ceph? Thanks, Duncan
