I have an add_custom_command in a subdirectory, and I'm trying to use<br>
that output as a dependency in a parent directory.<br>
<br>
Unfortunately, the parent directory doesn't see that I made a rule<br>
(add_custom_command) for the file in the subdirectory.<br>
<br>
<br>
top level CMakeLists.txt:<br>
...<br>
add_subdirectory(sub1)<br>
<br>
add_custom_target(generate ALL<br>
DEPENDS ${CMAKE_BINARY_DIR}/myfile.txt<br>
)<br>
<br>
sub1/CMakeLists.txt:<br>
add_custom_command(OUTPUT ${CMAKE_BINARY_DIR}/myfile.txt<br>
COMMAND ${CMAKE_COMMAND} -P ${CMAKE_CURRENT_SOURCE_DIR}/genmyfile.cmake<br>
WORKING_DIRECTORY ${CMAKE_BINARY_DIR}<br>
)<br>

I would just do the add_custom_target in the same CMakeLists where you<br>
do the add_custom_command. That target will still be available from your<br>
top-level CMakeLists. I use this approach all over the place.<br>

Unfortunately, I have several directories that all pool their files into the same target. I don't want to have a single target per file as this would clutter up Visial Studio projects quite quickly.<br>
<br>
Unless there's a different way to make the add_custom_command behave globally I'll have to somehow call this function only from the directory I call add_custom_target from. :(</blockquote><div><br>See the thread titled "problem with add_custom_command / add_custom_target in different directories" from a month ago. I had the same exact problem. There were two suggested solutions.<br>
<br>1. Make add_custom_command and add_custom_target be in the same directory<br>2. Create helper targets using add_custom_command and add_custom_target along the way and then add them to a global target.<br><br><a href="http://www.cmake.org/pipermail/cmake/2009-February/027314.html">http://www.cmake.org/pipermail/cmake/2009-February/027314.html</a><br>
