[CMake] Dependency for launching an application

[Andreas Haferburg]

Sure. Example:

add_library(common MyFancyString.cpp)

add_executable(parent parent_main.cpp)
target_link_libraries(parent common.lib)

add_executable(child child_main.cpp)
target_link_libraries(child common.lib)
add_dependencies(parent child)

Now I make a change to MyFancyString.cpp, select the parent project, and hit F5. Both executables 
use MyFancyString, so both need to be re-built.

What happens is that common is built, then child, then parent, then parent is executed.
What I'd like to happen is that common is built, then child+parent are being built concurrently, and 
as soon as both are done, parent is executed.

I hope it's clearer now.

Regards,
Andreas

So when using F5 in Visual Studio, child.exe is built first, then parent.exe, then parent.exe is launched. Is it possible to set this up such that child.exe and parent.exe are built in parallel before launching parent?
