</style><p class="MsoPlainText">Hi JD,</p><p class="MsoPlainText">Busy day, at a conference all day, and just got a chance to look into this.</p><p class="MsoPlainText"><br></p><p class="MsoPlainText">Unfortunately, no, the "pretty much make sure" part actually doesn't.</p>
<p class="MsoPlainText"><br></p><p class="MsoPlainText">With the add_dependency in place on the executable, to bind it to the external target, still, the external target is not generated before the rc is compiled. The interproject dependency is correct in the output (i.e. I see that bbs PROJ has a dependency on externalDependency PROJ) but the project is not invoked at the right time.</p>
<p class="MsoPlainText"><br></p><p class="MsoPlainText">so this:<br></p><p class="MsoPlainText">add_executable( cm_bbsExe WIN32 ${SOURCES} )<br>target_link_libraries( cm_bbsExe winmm ... )<br></p><p class="MsoPlainText">add_dependencies( cm_bbsExe externalDependency )<br>
<br></p><p class="MsoPlainText">behaves like this:</p><p class="MsoPlainText"></p><p class="MsoPlainText">myExe : bbs.rc</p><p class="MsoPlainText">myExe : externalDependency</p><p class="MsoPlainText"><br></p><p class="MsoPlainText">
which leaves the relationship between the externalDependency and bbs.rc undefined. 50/50, and it fails. I suspect that VC plods along, resolving it's dependencies, and it gets to the RC dependency before it gets to the externalDependency.<br>
</p><p class="MsoPlainText"><br></p><p class="MsoPlainText">Perhaps the problem is that when cmake scans the RC file, it doesn't understand how to resolve the included file that does not exist; or does not equate it to an external dependency ? Even telling it that it's generated does not help.</p>
<p class="MsoPlainText"><br></p><p class="MsoPlainText">SET_SOURCE_FILES_PROPERTIES(${EnterpriseDir}/lib/rsrc/msg00001.bin PROPERTIES GENERATED 1)</p><p class="MsoPlainText"><br></p><p class="MsoPlainText"></p><p class="MsoPlainText">
What I need is either to make cmake realize that externalDependency and msg00001.bin are one and the same (so that it sees the dependency), or to bind the inter-project dependency explicitly to the RC file that includes the bin file.</p>
<p class="MsoPlainText"><br></p><p class="MsoPlainText">Other than that, my only other option is to set up the resource compile as a custom rule. <br></p><p class="MsoPlainText"><br></p><p class="MsoPlainText">Is there any plan to allow file-level dependencies to be specified in cmake ? And/or is there another option ?</p>
<p class="MsoPlainText"><br></p><p class="MsoPlainText">Thanks again for all your help with this.<br></p><p class="MsoPlainText"><br></p><p class="MsoPlainText"><br></p><p class="MsoPlainText"><br></p>
