[CMake] Having problems getting started

[blinkeye]

I guess the following would suit your needs too:


#  AUX_SOURCE_DIRECTORY: Find all source files in a directory.

   AUX_SOURCE_DIRECTORY(dir VARIABLE)

Collects the names of all the source files in the specified directory 
and stores the list in the variable provided. This command is intended 
to be used by projects that use explicit template instantiation. 
Template instantiation files can be stored in a "Templates" subdirectory 
and collected automatically using this command to avoid manually listing 
all instantiations.

It is tempting to use this command to avoid writing the list of source 
files for a library or executable target. While this seems to work, 
there is no way for CMake to generate a build system that knows when a 
new source file has been added. Normally the generated build system 
knows when it needs to rerun CMake because the CMakeLists.txt file is 
modified to add a new source. When the source is just added to the 
directory without modifying this file, one would have to manually rerun 
CMake to generate a build system incorporating the new file.
