Hello again,
I am slowly porting a complicated project to cmake. I have an acyclic
graph of dependencies and "shared" build directories and I have trouble
generating VS slns. A simple example (the real build is way more
complicated):
liba/include.cmake:
get_filename_component(liba_dir ${CMAKE_CURRENT_LIST_FILE} PATH)
add_subdirectory(${liba_dir} ${liba_dir})
include_directories(${liba_dir})
link_libraries(liba)
liba/CMakeLists.txt:
add_library(liba a.cpp)
exea/CMakeLists.txt:
include(../liba/include.cmake)
add_executable(exea x.cpp)
exeb/CMakeLists.txt:
include(../liba/include.cmake)
add_executable(exeb y.cpp)
proj/CMakeLists.txt:
add_subdirectory(../exea ../exea)
add_subdirectory(../exeb ../exeb)
The idea here is that libraries use 100% modular include files. When I
run cmake I get this in .sln:
Project("{8BC9CEB8-8B4A-11D0-8D11-00A0C91BC942}") = "ZERO_CHECK",
".\ZERO_CHECK.vcproj", "{CDAEE59D-0373-4F41-9CF9-8DFA13581522}"

As you can see, the dependencies are correct, but liba is generated
twice. Visual studio complains about duplicates, but it seems to work ok
regardless. Is this a bug? Am I breaking some unwritten rules here? What
about other generators, like xcode, ...
thanks
