# Make an explicit list of all source files in `CMakeDemo_SRC`. This is important
|
||
|
|
# because CMake is not a build system: it is a build system generator. Suppose
|
||
|
|
# you add a file foo.cpp to src/ after running cmake .. . If you set
|
||
|
|
# `CMakeDemo_SRC` with `file(GLOB ... )`, this is not passed to the makefile;
|
||
|
|
# the makefile doesn't know that foo.cpp exists and will not re-run cmake. Your
|
||
|
|
# collaborator's builds will fail and it will be unclear why. Whether you use
|
||
|
|
# file(GLOB ...) or not, you will need to re-run cmake, but with an explicit
|
||
|
|
# file list, you know beforehand why your code isn't compiling.
