  Changed paths:
    M raster/CMakeLists.txt
    M raster/r.lake/Makefile
    M raster/r.lake/main.c
    M raster/r.lake/tests/r_lake_test.py

  Log Message:
  -----------
  r.lake: Reject seed coordinates north or west of the region (#7899)

* r.lake: Reject seed coordinates north or west of the region

The conversion to a cell index truncated towards zero, so a coordinate
less than one cell north or west of the region gave index 0 instead of a
negative value and passed the check below zero. Such a seed was silently
moved to the first row or column instead of being rejected.

* r.lake: Link libm for floor()

Previous commit added a call to floor() but r.lake was not linked
against libm, so the CMake build failed with an undefined reference.
Add the math library to both build systems, as other raster modules do.
