cmake: Check dependencies one by one 

It was currently done all at once. Therefore, the error message was:

CMake Error at /usr/share/cmake/Modules/FindPkgConfig.cmake:415 (message):
  A required package was not found

With no further information besides the full dependency list.

With this change, it will print the missing package.

Closes https://github.com/awesomeWM/awesome/pull/1253.
