If I use such a script for comparing time stamps of input and output files, I would need to rewrite every cmakelists.txt that uses add_custom_command, and execute the needed commands only if input file is older than output,or maybe I did not understand you idea with the script. This seems like a lot of mess for something that cmake should do. <br>
<br>Also is anybody experiencing this issue with vs2010 generator ?<br>Can anybody confirm that this is bug with vs2010 generator, and maybe some workaround ?<br><br>One more observation:<br>This problem seems to happen only when the output file goes to subdirectory in PROJECT_BINARY_DIR, in the example the subdirectory is PROJECT_BINARY_DIR/$(ConfigurationName). <br>
<br>If I put the generated file to go straight under PROJECT_BINARY_DIR than everything works ok. Also if I put the generated files to go under PROJECT_SOURCE_DIR or its subdirectories everything works well.<br><br>Thanks<br>

</div></div>Was just about to mail this list with the same problem, but using<br>
Makefiles on linux so its probably not build system spesific.<br>
Basically the command to generate always runs even if the inputs are<br>
older then the outputs.<br>
<br>
The only work around I can think of is to write a cmake script which<br>
is called rather then the generator directly, this cmake script can do<br>
the file comparisons to work out if generating the files is really<br>
needed, but would prefer if this wasnt needed.<br>
