Finding the search directories for a project/target?

[Kazade]

Hi, I'm writing a CMake project generator plugin (which generates a CMakeLists.txt file for the workspace). I need to somehow get a list of include/library search directories for each project/build target... how do I do this with the SDK?

Thanks,

Luke.

You might want to have alook at the sources of the cbMakeFileGen-plugin (see this thread), it does something similar.

Also GetCompileCommands in directcommands.cpp  (part of compilergcc-plugin) can be a good starting point.

I found a way to do this before I saw your reply

Basically, I got the ProjectBuildTarget for the project and the active target. Then I called target->GetIncludeDirs() and target->GetLinkLibs(). I then used popen() to call any pkg-config or wx-config commands and parsed the result. It seems to work well (although, it's probably a roundabout way of doing it)

I just want to tidy up a bit more before I post the plugin, but just as a teaser.. here is the output of calling the plugin on its own sources:

Code

ADD_EXECUTABLE( cmake_generator ${CMAKE_GENERATOR_SOURCES} )

At the moment it doesn't recognise the difference between libraries and applications so it's not quite right yet. But it compiles it just complains about "unresolved reference to 'main'"

Nice work Kazade
