The Free On-line Dictionary of Computing (30 December 2018):

compile time

    The period of time during which a program's
   source code is being translated into machine code, as
   opposed to run time when the program is being executed.  As
   well as the work done by the compiler, this may include
   macro preprocessing as done by cpp for example.  The final
   stage of program construction, performed by the linker,
   would generally also be classed as compile time but might be
   distinguished as link time.

   For example, static data in a C program is allocated at
   compile time whereas non-static data is allocated at run
   time, typically on the stack.
