[CMake] Setting dependencies between libraries (cmake projects)

[Ludovic Hoyet]

Hi,

I am using cmake to build an application made up of a dozen projects. We
use cmake to automatically generate solutions for x86, x64, and both VS
2005 and 2010.

Here is an idea of our organisation:

   - a.lib, which has no dependency
   - b.lib, which has no dependency
   - c.lib, which depends on a and b
   - d.dll, which depends on c

Each project lies in its own subdirectory, and has its own CMakeLists.txt
file. In order to keep track of the lib/dll generated for our different
platforms, we automatically post-fix each lib/dll with _x86/_x64 and
_vc80/_vc100 (e.g., a_x86_vc100.lib), and with an _d for debug (e.g.,
a_x86_vc100_d.lib).

In the CMakeLists.txt files, I use target_link_libraries to link each
target with the corresponding libraries, for instance:

 TARGET_LINK_LIBRARIES( c debug a_${VS}_${PLATFORM}*d optimized
a*${VS_DIR}*${PLATFORM}
debug b*${VS}_${PLATFORM}*d optimized b*${VS_DIR}_${PLATFORM})

In Visual Studio, the different "Project Dependencies" between the various
projects do not appear. I wonder if there is something I miss, or if it is
simply not compatible with our library post-fix. I also tried to
use ADD_DEPENDENCIES(c a b) but it does not seem to work either.

Does anyone has an idea how to solve this?

Cheers,
Ludovic
