So when the add_custom_command executes "App" it wont be able to resolve the dependencies to lib1 and lib2. If I only had one dependency I could possibly set the working_directory to the path of lib1 and use the absolute path of the "App" for the command. That would probably work but not with multiple dependencies.</span></div><div><font face="arial, sans-serif"><br></font></div><div><font face="arial, sans-serif">Your second example might do the job but wont be accepted as a solution in our company.</font></div><div><font face="arial, sans-serif"><br></font></div><div><font face="arial, sans-serif">regards, Lars<br></font><div class="hm HOEnZb"><br></div><div><div class="hm HOEnZb"><hr>Date: Wed, 19 Nov 2014 14:10:07 +0100<br>Subject: Re: [CMake] ADD_CUSTOM_COMMAND Application dependency<br>From: <a href="mailto:angeliki.chrysochou@gmail.com" target="_blank">angeliki.chrysochou@gmail.com</a><br>To: <a href="mailto:laasunde@hotmail.com" target="_blank">laasunde@hotmail.com</a><br>CC: <a href="mailto:cmake@cmake.org" target="_blank">cmake@cmake.org</a></div><div><div class="h5"><br><br><div dir="ltr">Hi Lars,<div><br></div><div>What if you provide the working directory to <span style="font-family:arial,sans-serif;font-size:13px">ADD_CUSTOM_COMMAND like this:</span></div><div><span style="font-family:arial,sans-serif;font-size:13px"><br></span></div><div><div><font face="arial, sans-serif"> add_custom_command(</font></div><div><font face="arial, sans-serif"> OUTPUT <output></font></div><div><font face="arial, sans-serif"> COMMAND command_to_be_executed <arg_1> <arg_2></font></div><div><font face="arial, sans-serif"> DEPENDS ${lib1} ${lib2}</font></div><div><font face="arial, sans-serif"> WORKING_DIRECTORY ${EXECUTABLE_OUTPUT_PATH}</font></div><div><font face="arial, sans-serif"> VERBATIM)</font></div></div><div><font face="arial, sans-serif"><br></font></div><div><font face="arial, sans-serif">Would it work?</font></div><div><font face="arial, sans-serif"><br></font></div><div><font face="arial, sans-serif">Otherwise a trick (more like a hack) like the following might be useful:</font></div><div><font face="arial, sans-serif"><br></font></div><div><font face="arial, sans-serif"><div> add_custom_command(</div><div> OUTPUT <output></div><div> COMMAND PATH=$ENV{PATH}:<more_paths> ENVIRONMENT_VAR=<some_other_value> && command_to_be_executed <arg_1> <arg_2></div><div> DEPENDS <dependency_1> <dependency_2></div><div> WORKING_DIRECTORY <working_dir></div><div> VERBATIM)</div><div><br></div><div>This sets the PATH temporarily during the execution of the command, where you could possibly add the paths to the libraries you need.
